Even sillier and less useful than WiiSpray, Halo is a spray can-style flashlight designed for “graffiti artists” looking for even more impermanence in their work. Designed by Paris-based Aïssa Logerot, the light-writing contraption is powered by shaking, features a selection of LED caps to change the can’s color, and has nothing on the high powered L.A.S.E.R. developed by the Graffiti Research Lab.
