New Piece: Termitarium

November 5, 2025

https://www.extrasleepy.com/work#/termitarium/

Slice up a pest-eaten piece of wood, embed a gradient of LED light in the center, and you might end up with something like this illuminated sculpture. Termitarium features wooden levels fragmented with CNC-chewed tunnels, creating a map-like pattern that catches light in unexpected ways. Two LED sources, projected at each other, gradually change color to create a Turrell-like gradient throughout a frosted glass tube in the center of the piece. Each diffusing layer is painted a different pastel color, giving the piece a colorful sculptural presence when off, and adding to the reflected color variation when on. The cast concrete base sits on thin felt, while a pierced river rock weighs the light blue power cord in place—adding another natural sculptural feature. Slide the slightly hidden switch, and be reminded that natural deterioration often provides the most compelling visuals.

New Pieces Summer 2024

September 3, 2024

Inspired by the product design section of SFMOMA's Art of Noise exhibition, I decided to get a little funky with my amplifier design skills. Decent Vibrations (yes, a nod to the Beach Boys ; )) is a small portable Bluetooth amplifier with a large on/off switch and a giant lumpy volume knob because why not? The base is cast concrete, and the body is texture-painted 3D-printed PLA. The piece is rechargeable, lasting many hours, longer than an unedited drone-metal double album––way longer.

Sometimes, you need to lump around and take in a little abstract art. And what if that abstract art was a little lumpy, too? Even better, what if it changed every six hours so you could contemplate a new maze of lines and shapes? Lumpstraction provides all that. A CNC-cut wood texture-painted sculpture with an embedded black and white e-ink display, this piece will delight your abstraction appetite without keeping you awake at night (Literally, there's no illumination).

Thank the gods for Modern Digestion

September 4, 2022

Modern Digestion is a nod to the intestinal tract and all the microbiota working in miraculous ways to perpetually break down, absorb, or pass the extraordinary collection of natural, synthetic, planned, and unintended items we put down our esophagus. From prehistoric to recently engineered foods, the gut keeps it all moving.

The light sequence, composed of 26 programmable LEDs, fades at random intervals, in a random order, through meditative warm and cool tones. This piece can operate plugged into a USB outlet or charged for five or more hours of untethered operation. Programmed with CircuitPython.
