Check out this recent installation by Norwegian artist Børre Sæthre. It can be seen at the PS1 in Queens. The exhibit is a highly immersive experience infuence by an 2001: a space odyssey aesthetic with flashing lights and strange noise and odd visual affects such as the cloudy unicorn - at times the glass is perfectly transparent, at times the glass appears hazy and obscure.
See a video of the exhibition here http://blip.tv/file/1492267. The unicorn piece is at the end, around 3:15.
