I heard about this on MPR Marketplace this morning while on the way to work. It's a 3D pen that writes in the air. Then I got to work there was a mention on The Presurfer of the pen. They had a Kickstarter page and they were looking for $30,000. It was at $900,000 when they did the story, not when it aired this AM, now it's up to $1.2 million. It's kind of neat thing but not sure I would need one.
