The other day i stumbled across this guy's very neat video of a thing he made called the Aurora 9x18 and it's simply beautiful. It is a circular circuit board with 9 rings of 18 RGB LED's controlled by a micro controller and the sequences it shows are quite awesome.
Here it is:
He also has one with just one ring of 18, the Aurora Mini 18:
He also has another one that is a bar of just nine.
I posted these videos because they define exactly what awesome is. They are also hypnotic, and who doesn't like hypnotic videos?!?!
