Halftoned animated gif

This is the last gif for a while, I'm simply wasting time now.

In order to produce a larger image with smaller file size (though still a sizeable 5.5MB) I created a layer when creating this gif in Gimp and rendered a grid with lines 1 pixel wide spaced 2 pixels apart (so every other row and column are painted). Then "selection from alpha" on this layer and delete from each of the animations layers. You are left with a bunch of layers that are mostly alpha right now, just little dots of color floating there now. I then remove the alpha channel from each layer with a background color of black. Finally switch to indexed color mode with no dithering, and then optimize animation for gif.  This particular image has 466 layers and runs at 60fps.
