All I can say is wow, some of these animations are amazing. Congrats to all the winners. My personal favourite is second place. It lacks a little of the visual artistry of the winner but the technical aspects are amazing. Shaking camera, explosion of light, nuclear cloud. Animated. IN 512 bytes? Awesome work. The idea to use a sphere instead of a sky sphere so the sky glows for an instant when the explosion happens is really inventive.
