Here’s the latest thing I’ve made using those nifty color-changing LEDs. It’s another wall-hanging piece, broken into a grid of pixels that cycle through various colors. One might imagine that it’s continually outputting a series of randomly-generated low-resolution computer icons. But if you lay it down flat one could also imagine that it’s a very small disco floor. You can get a vague sense of how it looks by watching this Flickr slideshow.
