Wall Papers

Individually the cameras aren't heavy (5.5 oz each), but slap two of them together and attach them to the 3D base and suddenly you have about a pound of equipment strapped to your head. Pair that with the considerable wind resistance the combination generates at speed and, well, it's safe to say you'll notice their presence -- unless you happen to have a neck that's frequently mistaken for a tree trunk.

That said, if you don't mind the extra heft it's quite possible to ride, walk, swim, or whatever with the cams attached to your head, as we managed to do for a few separate videos. It's at this point where the reality of the situation begins to interfere with the experience: what you're working with is two separate video cameras that, other than a plastic clamp, are completely disconnected. It's entirely possible to point the remote at the pair, hit the record button, and have only one start. With the very wimpy beeps that these emit when they start recording it's difficult to hear whether either started filming, and since they both make the same pitch it's impossible to tell if they're both capturing footage without looking at them -- hard to do when they're on top of your head.
