Looked interesting so Googled around a bit. Looks like a successful Kickstarter project that maybe didn't end up as quite as neat as the product looked in the video. Must be excess stock sitting around now. Anyway, found one at

http://www.utrechtart.com/

They are running a 40% off sale with coupon code SUPER. Total cost, with shipping came out to $33.00. A bit better than what is offered here.
