How To: Digital Light Graffiti
This interesting hack involves the modding of a disposable camera into a portable ‘light graffiti’ projector able to display any image or words you so choose. The site contains a video of the defacing in action and lots of info on how to build your own. Supposedly this graffiti projector will be able to last 2 days - plenty time for advertising that rave at your local abandoned warehouse or for any other sticking-it-to-the-man type message.
