Is this related to the webcam 3D scanner video that was in the news about s year ago? I'd be interesting to check out.

Looks like it just uses the reflected intensity to estimate the depth, then pastes the original colormap on top of that? Incredibly clever and simple hack.

Cool app. But I have a pet peeve with information pages that only provide video as a description. Whilst I understand that especially for an app like this, the best 'information' is to demonstrate how it works via a video, it doesn't help people a. just want to get a quick one line explanation of what your app does and/or b. can't watch the video at the time (slow connection, work restriction etc).

If I hadn't been at home, I would have just left the page and moved onto to something else - missed sale.

Can the iphone modulate the intensity of its light via software?

Thanks for the feedback. I was expecting to have this weekend to pull everything together but Apple approved the app in 2 days (which is great, but 5x faster than for my previous submissions).

I assume it displays varying shades of full-screen grey. There's no public brightness API. You're free to do it outside the app store, of course. (you can find the private API calls pretty easily on Google)

The fact that this only works in the dark made me wonder, how much of what the Kinect does could be possible on an iPhone, and what would be needed to get there? 2 Cameras? What else?

It's the intensity of the reflected light off the face received by the phone that varies, not the light put off by the screen of the phone. As lliiffee said, incredibly clever.
