The Halo LED Spraycan Let’s You Graffiti Without The Paint
You might have seen those tv commercials on your tubes a few years ago featuring light swirls that magically make up words or images; or your friend showed you his portfolio of photographs with glowing light swirls on dark backgrounds. While these can be achieved through long exposures and stop-motion animation, the Halo LED spraycan will let you do this with more style and flare. It is a DIY project by Aissa Logerot, who made use of light emitting diodes, rather than paint. That means no permanent damage to anything, and no paint to deal with.
Obviously it only lasts temporarily and it even charges itself when shaken like a true graffiti spray can should be!
