Lens Blur in the new Google Camera app
I've created a parallax viewer for lens blur photos. It's an open source web app available at http://depthy.stamina.pl/ . It lets you extract the depthmap, works on chrome with webgl and looks pretty awesome on some photos.
There is quite a few things you can do with this kind of images, so feel free to play around with the source code on github https://github.com/panrafal/depthy
