Someone has already built a measuring tape app out of this thing: https://www.youtube.com/watch?v=nQpEWv9_6Cg. Not exactly mapping as you're describing, but it's an interesting use case.

Interesting - thanks for sharing.

I actually thought the trajectory app was pretty cool.

actually question - that video shows an ipad - does that mean you don't need the fancy new camera to do that?
