Qonworld for beautifully and whimsically depicted state of destruction.
euio's version of supercollider doom for elegance and clarity, plus a bonus for finding a great way to use side-by-side maps in the challenge without falling back on before/after
If I could have voted for 3, the third would have gone to Sapiento. That was a really nice Atlantis, and a nicely messed up Atlantis.
Congratulations to all! We made maps! Whee!
