LeoneLabs created PixelBrite, a study in pixels.  This amazing build is more than a light table.  It’s a digital Lite-Brite, minimalist light sculpture, a disco light, a sound reactive light show all rolled into one.

With batteries and a slot for and SD card to stream patterns without a computer, PixelBrite can act as a standalone light.  You can also plug it into a MIDI controller and have a interactive light show.

The Instructible page on the project is well worth reading.  It’s incredibly detailed and contains not only build details (like a complete bill of materials spreadsheet) but some information on color theory and display science as well.

The project is open source with the code available on GitHub.
