Courtesy of Daniele Gallifa's Mentegrafica, a video demonstration of Multi-User Interaction using Handheld Projectors. An update to the classic Ghostbusters toy, this set of position-aware hand held projectors lets users share information by shining light onto walls. Some of the smart details in the video include: sharing calendars by overlapping light from two projectors, adjoining projections to create larger screens, and blurring private information when outsiders are nearby. No mention of applicability to first person shooters.

The folks at Anchor optics must have figured out that if you give away more than thirty pdfs of classic science project books involving optics, people who want to do the projects will know where to shop. My favorite: Fun With Fresnel Lenses (22.9 mb pdf).

Parasitic Subway Projector: High concept German art students cram a Mac mini and a projector into a suitcase and mount it to the side of a subway car with suction cups. The resulting images, projected onto the tunnel walls, make for a fascinating work of public art. [QuickTime] Link via: The Unofficial Mac Weblog
