I thought this was a nicely put together spoof of kick starter, I'm flabbergasted how that has raised so much money. The people using it look like the heaven's gate cult photos from years ago.
But on the topic at hand, I would buy one of these, or at least, I definitely would if I were still in High School. On state standardized test days (normally a half-week occurring a few times per year), I (and many peers) would inevitably finish in about 2 of 4 hours. Of course we were obligated to stay in the room and remain completely silent for the entire 4, so I would fold a jacket such that it fashioned a very poorly-functioning version of this.
The main issue while using a jacket was having proper respiration between my face-down head and the desk. If this product solves this when it comes out (maybe I can try it out somewhere? Brookstone or some such?), I can see myself considering it.
On a more serious note, this is really a "how to get your stuff stolen" hat.
Club individual on head, yank thing, run away.
I was thinking more along the lines of Guantanamo, but... hey, it was good for a morning chuckle.
