Can you make music from Joshua trees — or is that wild science? Yes.
Artist Scott Kildall waves his microcontroller over a Joshua tree, recording wavelengths of light that are not perceptible by humans.

The artist Scott Kildall is waving his hand over the contours of a Joshua tree, just inches from its spiky green, bayonet-like leaves.
“If I get too close to it, it will prick me and draw blood,” he says. “And it’s done that before.”
In his palm, he has a microcontroller — just about the size of a credit card. It’s got a few wires sticking out, and an infrared sensor, which picks up wavelengths of light just beyond what the human eye can perceive.
“It’s kind of like magic,” Kildall says. “And the magic is just revealing something that’s right beyond our levels of perception.”
The magic is part of Kildall’s latest sound installation — a work he calls Infrared Reflections. He developed the piece as an artist-in-residence at Joshua Tree National Park this spring, and it transforms near-infrared light bouncing off the iconic scraggly yuccas into a shimmering mosaic of otherworldly music — essentially turning the Joshua tree into an instrument.
Kildall is neither a computer scientist nor a musician, though he does play the ukulele. This artwork relies on both disciplines, as Kildall needs to build sensors, route their data to a computer, process and smooth that data, and convert it all into something beautiful for the ear.
“With art and technology, you have to constantly think about wearing multiple hats. Are you an IT person? Are you an artist? And you have to be able to troubleshoot on the fly,” he says.
The installation relies on a fundamental interplay between the sun and the Joshua tree. When sunlight hits the plant, cells in its healthy leaves soak up lots of red and blue light, and reflect back most of the green – which is why the clusters of piercing leaves at the end of the Joshua tree’s branches appear green to the human eye. (It’s also why most plants on Earth appear green to us.)

But other types of light rain down on the Joshua tree too, including wavelengths we can’t see, like near-infrared light. The plant’s shaggy, grayish-brown bark doesn’t reflect much of that infrared light, but its healthy leaves — packed with compounds like water, carbohydrates and defense chemicals — reflect much more. And that’s exactly what Kildall sees as he passes his sensor from the yucca’s dead bark to its green, leafy buds.
“Beyond our perceptions lies a whole realm of invisible data,” he explains. “And so what I do is I find some sort of invisible phenomena such as water quality or air quality or infrared light reflection, and then map that data into sounds, so that we can hear that data.”
That technique is known as sonification, and Kildall has previously designed installations that sonify water flow in trees, or tap into the electrical signals of mushrooms. Infrared Reflections follows in that vein, but it’s much more site-specific — it’s meant to be played on the Joshua tree, which is endemic to the Mojave Desert.
Kildall needs a speaker and a bag of equipment on site to make his music.

With that in mind, earlier today Kildall lugged his laptop, a box of electronics and a giant speaker into a field full of Joshua trees at the Arthur B. Ripley Desert Woodland State Park, north of Los Angeles.
Gusts of wind scream through the high desert here, and Kildall eyes individual Joshua trees with the eagerness of a kid at Guitar Center, ready to pick out an axe.
“I see one Joshua tree that’s about a hundred feet away that is moving a little bit in the wind and has multiple leafy sections and bark sections,” he says. “And that one really looks like it is asking to be sonified.”

After a short walk, Kildall sets down the speaker and begins fiddling with his laptop. It’s perched on a camp chair, in direct sun, and refuses to boot up — a reminder, Kildall says, of how preparing for a field installation is like planning a NASA space mission (though with non-lethal stakes.)
“You want to reduce the number of points of failure. And so with the system I have, I have backup electronics, I only have one laptop. So that’s the only point of failure that I’m really worried about.”
But not to fear. The machine soon boots up, along with a local Wi-Fi network — which connects the small infrared sensor to the computer — and Kildall is ready to rock.

Here’s the same landscape viewed through a thermal infrared camera. It captures a different part of the infrared spectrum from what Kildall is picking up with his sensor, but gives a sense of how these plants appear differently when viewed at different wavelengths of light.

As he caresses the air just above the tree, the yowling of a theremin rises and falls from the speaker, lending an eerie soundtrack to the already alien-looking landscape. A few hikers walk by, but seem unphased by the guy performing reiki on a Joshua tree. The high desert is known for its eccentrics, after all.
Kildall has designed three more “instruments” to be played like this, along with the theremin sound.
His favorite combines the drone of a theremin with spiraling arpeggios.
Another sounds more like haunting electric guitars, reverberating in a cathedral.
The final sound is more pared-back and simple — resembling a kid plinking at the piano.
“In some ways, it feels a little bit more direct and accessible because we all kind of understand how to press notes randomly on the piano,” Kildall explains. “And as I move the sensor over these sort of leafy spots in the sun, those will produce a higher pitch on the piano.”
As he slides the sensor further down the branch, to the bark, the notes get lower and lower, moving deeper into the bass clef.
Kildall holds his device a few inches above a spiky Joshua tree to avoid getting pricked.

It’s a fascinating way to make music. The infrared-sensing technology at the heart of the work also happens to be something scientists have employed for decades.
“From our aircraft or satellites, we use it to separate the living vegetation from the dead vegetation,” says Greg Asner of Arizona State University in Hawaii. “That’s very important in a grassland — is the grassland dry and ready to go up in smoke in a fire, or is it wet and green and living? And so we can translate that to fire fuel load for grasslands.”

Asner has also soared above the Amazon basin, measuring infrared signals from a plane — which allows him to tease out individual tree species, based on the fingerprints of infrared light that bounce off the trees.
“When I fly over a tropical rainforest with the infrared sensors, the maps literally are like Willy-Wonka-candy-store-style variation. They are amazing to look at,” he says.
“So there’s this enormous diversity of plants when you look at them in infrared light. And unfortunately, a lot of people just see them as green because that’s all we can see with our limited eyesight. There’s much more variety out there. And it’s a very beautiful world when you look at it in the infrared.”
Asner says he’s thrilled to see artists now experimenting with the same technology.

“Our studies for decades now have been stuck in the halls of science. And this will help translate what we have come to understand, utilize, love as scientists — it’s going to translate it to a much wider audience.”
Kildall says, in some sense, that’s his goal.
“One of the things I like to do is to engage people with nature and issues of climate change and issues of ecology through means other than science articles,” he says. “Science articles are great. I read them all the time. However, they don’t engage people on a more visceral storytelling level, as artwork does.”
And though this installation was conceived and developed with the Joshua tree at its center, it could work with the infrared reflections of other plants, if Kildall calibrates his code — which is a good thing, since Kildall calls San Francisco home.
“There aren’t any Joshua trees in San Francisco, so I might have to go to Golden Gate Park and see what I come up with.”
After retirement, Paul Gripp still visited the nursery often, helping with weeding, as he’s doing here in this file photo, or just talking with customers.

Orchid expert Paul Francis Gripp, a renowned orchid breeder, author and speaker who traveled the world in search of unusual varieties for his nursery, Santa Barbara Orchid Estates, died in a Santa Barbara hospice center on Jan. 2 after a short illness. He was 93.
In a Facebook post on Jan. 4, Gripp’s sister, Toni Gripp Brink, said her brother died “after suffering a brain hemorrhage and loss of consciousness in his longtime Santa Barbara home. He was surrounded by his loving family, day and night, for about a week in a Santa Barbara hospice before he passed.”
Gripp was renowned in the orchid world for his expertise, talks and many prize-winning hybrids such as the Santa Barbara Sunset, a striking Laelia anceps and Laeliocattleya Ancibarina cross with rich salmon, peach and magenta hues that was bred to thrive outside in California’s warmer climes.
In a 2023 interview, Gripp’s daughter, Alice Gripp, who owns and operates the business also known as SBOE with her brother, Parry, said Santa Barbara Sunset is still one of the nursery’s top sellers.

Gripp was a popular speaker, author and avid storyteller who talked about his experiences searching for orchids in the Philippines, Myanmar (then known as Burma), India, the high Andes, Mexico, Guatemala, Brazil, New Guinea and other parts of the world, fostering exchanges with international growers and collecting what plants he could to propagate, breed and sell in his Santa Barbara nursery.
“Working in orchids has been like living in a dream,” Gripp said in a 2023 interview. “There’s thousands of different kinds, and I got to travel all over to find things people would want. But the first orchid I found? It was in Topanga Creek, Epipactis gigantea, our native orchid, and you can still find them growing in [California’s] streams and canyons today.”
Gripp was “one of the last orchid people who went looking for these plants in situ — where they occurred in nature,” said Lauris Rose, one of his former employees who is now president of the Santa Barbara International Orchid Show and owner of Cal-Orchid Inc., a neighboring nursery that she started with her late husband James Rose, another SBOE employee who died in January 2025.
These days, Rose said in an interview on Thursday, orchids are considered “something to enhance the beauty of your home,” but when she and her husband first began working with Gripp in the 1970s, “they were something that totally captivated your interest and instilled a wanderlust spirit that made you want to explore the species in the plant kingdom, as they grew in nature, not as produced in various colors from laboratories.”
She said Gripp’s charm and self-deprecating demeanor also helped fuel his success. “People flocked for the experience of walking around that nursery and learning things from him,” Rose said in a 2023 interview.
“Paul lectured all over the world, teaching people about different species of orchids in a very accessible way,” Rose said. “He didn’t act like a professor. He got up there with anecdotes like, ‘One time I climbed up this tree trying to reach a plant in another tree, and all these red ants infested my entire body, so I had to take off all my clothes and rub all these ants off my body.’ A lot of people’s lectures are boring as dirt, but Paul could command a room. He had charisma, and it was infectious.”
Gripp was born on Oct. 18, 1932, in Greater Los Angeles and grew up in Topanga Canyon. He went to Santa Monica College and then UCLA, where he earned a degree in horticulture, and worked as a gardener on weekends, primarily for Robert J. Chrisman, a wealthy Farmers Insurance executive and hobbyist orchid grower who lived in Playa del Rey.
After college, Gripp served a stint in the Navy after the Korean War, and when he got out, he called Chrisman, his old boss, who invited him to come to Santa Barbara and manage the orchid nursery he was starting there.

The nursery opened in 1957, with Gripp as its manager, and 10 years later, after Chrisman died, he purchased SBOE from the Chrisman family.
In 1986, Gripp and his then-wife, Anne Gripp, divorced. In the settlement, Gripp got their cliff-side Santa Barbara home with its breathtaking views of the Pacific Ocean, and his former wife got the nursery. When Anne Gripp died, her children Parry and Alice inherited the nursery and took over its operation in 1994, Alice Gripp said in 2023.
Gripp officially retired from the nursery, but he was a frequent helper several times a week, weeding, dividing plants, answering customer questions and regaling them with his orchid-hunting stories.
“Paul loves plants, but what he loves most in life is teaching other people about orchids,” Alice Gripp said in 2023. “He chats with them, and I try to take their money.”
Gripp wasn’t a huge fan of the ubiquitous moth orchids (Phalaenopsis) sold en masse in most grocery store floral departments, but he was philosophical about their popularity.
They’re good for indoor plants, he said in 2023, but don’t expect them to live very long. “A house is a house, not a jungle,” he said, “so there’s a 99% chance they’re going to die. But they’re pretty cheap [to buy], so it works out pretty good.”
“He used to say, ‘I’m an orchid man. I love every orchid equally,’ and he does,” his daughter said in 2023. “I don’t know if he would run into a burning building to save a Phalaenopsis from Trader Joe’s, but he told me once, ‘I’ve never thrown out a plant.’ And that’s probably true. When he was running things, the aisles were so crammed people were always knocking plants off the benches because they couldn’t walk through.”
Gripp is survived by his children and his second wife, Janet Gripp, as well as his sister Toni Gripp Brink. In a post on the nursery’s website on Jan. 5, the Gripp family asked for privacy.
“We are still very much grieving Paul’s sudden passing,” the message read. “If you would like to share your memories of Paul, please send them by mail or email for us to read in the days to come. We will welcome your remembrances and gather these into a scrapbook to keep at SBOE. We appreciate your understanding of our need for peaceful reflection at this time. In the coming weeks, we will announce our plans for honoring and remembering Paul with our orchid friends.”

DUARTE, Calif. — Veteran actor T.K. Carter, who appeared in the horror film “The Thing” and “Punky Brewster” on television, has died at the age of 69.
Carter was declared dead Friday evening after deputies responded to a call regarding an unresponsive male in Duarte, California, according to the Los Angeles County Sheriff’s Department.
Police did not disclose a cause of death or other details, but said no foul play was suspected.
Thomas Kent “T.K.” Carter was born Dec. 18, 1956, in New York City and was raised in Southern California.
He began his career in stand-up comedy and with acting roles. Carter had been acting for years before a breakthrough role as Nauls the cook in John Carpenter’s 1982 horror classic, “The Thing.” He also had a recurring role in the 1980s sitcom “Punky Brewster.”
Other big-screen roles include “Runaway Train” in 1985, “Ski Patrol” in 1990 and “Space Jam” in 1996.
“T.K. Carter was a consummate professional and a genuine soul whose talent transcended genres,” his publicist, Tony Freeman, said in a statement. “He brought laughter, truth, and humanity to every role he touched. His legacy will continue to inspire generations of artists and fans alike.”

Cosmic Cleavage …
Flaunts Boobs While Pushing New Fragrance
Published
Kylie Jenner‘s full-bodied new fragrance is out … and, she’s using her bust to promote it — pushing up her cleavage for the ad.
The model posed in the sleeveless red leather top which perfectly matched the fragrance bottle she held against her head.
Waiting for your permission to load the Instagram Media.
The star’s looking away from camera … though we imagine if she could see fans looking at the pic, she might tell them her eyes were up about a foot or so!
She captioned the post by telling fans the new smell is called COSMIC INTENSE … a spin-off of her original “COSMIC” which feels “warmer, creamier, and even more addictive.”
KJ’s gotta promote the perfume now because she’s not going to have much time to work on her business in upcoming weeks … as we imagine she’ll attend every awards show with her man, Timothée Chalamet.
As you know … Chalamet got handsy with Jenner shortly after winning the Critics Choice Award for Best Actor — grabbing her backside while sitting in the audience. He’d just said he loved her in his acceptance speech as well.
Maybe Chalamet will grab a bit of her cosmic cleavage if he wins a Golden Globe this weekend!
