Because I think most of the rest of you probably saw this on Facebook:

Edited 2/24 to replace link for updated video (original was deleted due to a minor typo in the title).
Edit: 2/25 the replacement video was taken down as well...I'll edit again if a third one goes up, but there are demos (somewhat less cool) on the website. Also, pricing is apparently $325 + $20 S&H each. I'm unfamiliar with these devices, so I looked to see what else is out there; the other models I saw are hand cranked, look heavier, but are about half the price and go flat for ceilings. Still, the speed alone would make it pay for itself on a sizeable job.
