Seems to be the week for different devices and approaches for interacting with virtual worlds, but my good friend Pais reminded me of the ingenious work of Johnny Lee which mimics stereoscopic vision on a 2D display:

He’s developed a number of Wii-related projects, including a multipoint interactive whiteboard.

Genius stuff, and it’s generated a stream of comments and follow-on development.

So now we have Fix8, Emotiv, and no doubt many others.
