Inspired by MisterWiiWii's "Hypnosis" project. It wasn't running fast enough on my computer because he used the swirl effect to make a spiral. This one just uses rotation and a spiral made in MS Paint. Stare at the center of the spinning spiral for about 30 seconds, then look at something else. I suggest setting speed to around 30 or -30. Positive numbers make the spiral "shrink" (causing other things to appear to grow). Negative numbers vise-versa.
