In 2010 we built the Illuminatrix which was featured on the MAKE blog. This was a 4′ x 4′ wall of LEDs showing hundreds of animations created by people from around the world at the Burning Man festival, you can still see its animations here http://cwd.co.uk/illuminatrix
This year we’ve gone bigger, and spherical! We’re building an 18′ geodesic dome with hundreds of LEDs and a beautiful skin to create a surface of light to surround and encompass the viewer.
We’ve detailed the full setup on our blog (www.delarre.net/posts/from-node-to-diode/) and will continue to cover the build process for the dome there. We’re still fundraising too, so if you want to contribute please do so at the IndieGoGo campaign at http://igg.me/at/diodome to win our undying love and affection!
