This is very cool technology. The company was formerly "Ocuspec". One break-through is using very inexpensive hardware (<$5 at RadioShack) to get that sub-mm resolution. At the other end of the spectrum, they can cover a football field (and more in the future). What they are showing now is just the beginning. Kudos to rolling out with an SDK. I can inly imagine what sorts of applications developers will dream up.
