Squarepusher: Pixel Breakout
Reader Michael Cook sends word of Pixel Breakout, a teeny-tiny flash game which is both exactly what you'd expect and pleasantly surprising. For the 60 or so seconds it takes you to complete it, you're pretty well rewarded. And yet now I am angry, because playing it's reminded me of an old, freeware, overwhelmingly psychedelic Asteroids clone where everything you shot or touched exploded in a shower of pixels and tinny noise. I think it began with an A. Is that ringing any bells for anyone? It definitely deserves a post of its own.
EDIT: Spheres of Chaos! That was it. And I see Alec "Greasy Cheetah" Meer wrote about it a whopping three years ago, right here.
