Laser tracking

Tonight I thought of using laser pointers on a projection to create a sort of interaction, much like the Graffiti Research Lab has done. Of course, this has been done before, I know it.

• Laser trail tracking, visuals / graphics, clubbing
• The GRL project, originating in street art; youtube, wikipedia
• All GRL’s stuff is open source, so here’s the laser tagging 2.0 howto
• A paper about multiple-point tracking (2003)
• An interactive data wall, military purposes…
