a few kbs of memory hold 3 minutes of animation and decoded with 1MHz CPU.

Apparently there's a NES version too.
I'll challenge anyone here to try to fit this into 4k (on whatever existing platform) - the music is repetitive enough that it'll compress really well (just as a test the ~250k MIDI of it I had went down to a bit over 8k with only 7z), and if you use a vector-based differencing encoding or pseudo-procedural generation for the animation, each frame might turn out to be <10 bytes.
