Spider Dot Grid

About

An eight-legged spider that follows your cursor around a grid of dots. Its body eases toward your pointer, and each leg figures out where its knee should bend on every frame. The feet step to the nearest dot with a little hop, and it always keeps at least four feet down so the walk looks natural. Move your mouse over it and it'll come after you.
