Laser-guided projection allows huge hilarious graffiti
Share
You take a laser pointer and use it to “draw” whatever you want to graffito on a building side. The projection system uses that as a template to place a gigantic version in the public eye. Hilarity ensues. But don’t just sit there giggling – build your own (or at least watch the video). [GT]
