Spinners

There's nothing too crazy going on here. I was just doing some experiments with bokeh and DoF compositing and trying to find an efficient method for rendering animations while avoiding the artifacts caused by FG/BG edges. I got something working here, but it's a bit of a pain and takes some planning. Next time I'll probably write a script which does most of the thinking for me, but for now I'm done with this effect. Enjoy!
