Saw some magnetic lights in a car magazine and thought I would do some research on them. Rather interesting, has anybody used them? There are other pretty cool lights as well. Thinking about getting a few.

I saw these when the Graffiti Research Lab came up with them a few years ago; You can do some pretty fun stuff with them, though I've never used them personally. Tossing them up on inaccessible steel structures and passing vehicles to entertain passersby sounds like the most fun. Their biggest drawback is that they are not re-usable (at least not the do-it-yourself ones).
