I try not to get sucked into unreleased product hype but when I saw the initial demo of the Leap Motion product, a box that sits in front of your Mac and reads your hand gestures Minority Report style, I bought one. The product is shipping later this month but they've been sending out units to developers for awhile and there are some really fun applications showing up. Today Brett Terpstra pointed out this video where a guy is controlling his lamp with hand gestures. This is pushing all of my nerd buttons. I wonder if John Lassiter has seen this.
