I've never traveled through space at light speed, but I imagine that standing in this LED tunnel is pretty close to the dizzying experience. The video is just plain awesome.
The name of the installation is Multiverse, and it was installed by artist Leo Villareal in a 200-foot-long tunnel in the National Gallery of Art in Washingtong DC. The entire thing features 41,000 LEDs that animate and move on their own, using randomness to ensure that no one will see the same configurations twice. Multiverse will be on display throughout 2009.
