Mac dock magnification effect on iOS

Bartosz Ciechanowski on his open source project MCSFishEyeView:

While the concept of the fisheye itself is not entirely new and everyone using OS X knows this effect from Dock, it seems completely underused in touch devices. We decided to bite the bullet and just roll out our own.

Bartosz also includes a walk through how how to properly scales the images for the fisheye effect.
