FGNOnline has posted a report on Lionhead's Black & White from ECTS, which they're reporting was being shown using a set of custom 3D glasses. Here's an excerpt:

The visuals this time were enhanced by a 3D facility that was truly amazing. Consisting of a monitor top sensor and a set of glasses the game could be viewed in genuine totally immersive 3D. "This will be pretty cool," said Molyneux. "The central unit should cost about £30 ($48) and the glasses will cost £20 ($32) per pair after that." If this is the genuine cost for a jaw-dropping interactive experience then it represents fantastic value.
