@jasoncoon of Evil Genius Labs sent me his new 8x8x8 LED Cube. This is a volumetric display made of 512 WS2812 LEDs and a PixelBlaze inside a frosted acrylic box. It was a kit; I soldered and assembled it over the last two days. The PixelBlaze came with many preprogrammed effects, including these three.
It looks even better in person -- the camera oversaturated on the bright parts.
I refrained from showing Munching Cube in the video, though one of the preloaded patterns is similar.
@jasoncoon is selling these on Tindie if you want a box of light in your own life.

PSA: the company Evil Genius Labs is a lie! @jasoncoon may be a genius, and he might even have a laboratory, but he completely fails at evil. He's the extremely responsive, helpful, anti-evil bespoke product vendor we most want to work with.
@jasoncoon I'm finally getting into writing shaders for my PixelBlaze/Evil Genius Labs LED cube. I call this one Bubble Phi. It uses the R₂ low discrepancy sequence to pick the colors, thanks to @mbr for showing it to me. (I've used R₁ color sequences in other projects.)
@dngrs Sorry, yeah. That was a little context-free. Here's the paper. It uses a generalization of the golden ratio (phi) to generate low discrepancy sequences. R₁ is for 1 dimension, R₂ is for 2D.

I used 2D points to pick the two hues in each bubble. The video is too short to show the effect very well, though.
