"Unbelievably cool." -- Beamer + Kamera + Laser = Massive Win

Huge lazer.jpg
immah charging mah lazer!


My jaw dropped when I watched this video of Graffiti Research Lab's laser graffiti system. You hold a laser pointer in the air, and draw whatever you want. A high-powered projection system (hidden in a van) "paints" the image on the surface of a building. Unbelievably cool. -- BoingBoing - Mind blowing video of laser-guided graffiti system

Video, wie das ganze in echt aussieht


A) Software der GRL Leute (Windows only)

B) Software aus Wien (Windows, Mac)

C) Future

  • svn
  • How about using recode it under Quartz Composer to add some special effects?
  • GRL is working on a new client-server based app, we'll switch to that and make funky clients for it. Any idea how it will work?

  • ~4-7k für den Beamer sind arg, laut GRL gehts aber auch mit dem 1.5k teil. Testweise funktionierts auch schon mit einem "normalen" Beamer.
  • 1k für die Kamera? Wir haben mit der eingebauten iSight eines MacBooks super Ergebnisse erzielt.
  • Die normalen roten Laserpointerchen gehen nicht, nicht, nicht!!!!!!!!!

Laser Safety

I've just received a 15mW green laser from WickedLaser, and I'm terribly afraid of the safety guidelines to not harm myself and others, could you explain a bit more about it?

  • is it safe to use indoor?
  • laser point is really bright when nearer than 5 meters, is it dangerous?
  • which is the best laser to use? links to laser shop
  • Laser Tag from GRL is perfect with its target far above heads, how to deal with a crowd when using laser?

making this possible

  • oneup (omfg-lets-do-this!, software, set-up)
  • mzeltner (opengl / 3d rotation haxxor)
  • sushimako (his majesty of beamer kingdom)
  • Overflo & Edmund (providing incredible laser power since 2007)
  • heise, weil sie uns gesagt haben, dass wir das machen, bevor wir's richtig wussten.

Weitere Ideen, was man mit Beamern machen könnt
