An exercise in chromatic aberration and catgirls.  Rather than having a slider like you'd find in some video games (or simply an on/off button), the slightly distorted colouring is achieved by literally (digitally) placing a transparent lense shaped object between the sibject and camera.

This seems to add a considerable amount to render time, and also makes it very hard to tell exactly where the camera is focusing on until it's had quite a bit of time cooking in the render oven.
