It’s an iPhone app for devices running iOS 5+ that takes video frames from the front camera and performs a vImageBoxConvolve twice to simulate a gaussian blur. It does this in realtime (well, ~15fps) and the slider sets the blur radius. The code to do this is remarkably small:

You can download and play with the Xcode 4.3 project here. The normal warnings of: this is not production code, it’s not pretty, at least it doesn’t crash, etc. all apply. Have fun!
