Azumanga Daioh

This here is the longest animation I've done so far - 263 frames. Nevertheless it was fun to make.

Order of entrance of the AD schoolgirls and teachers: Sakaki, Osaka, Tomo, Yomi, Kagura, Yukari, Nyamo, and then Chiyo-chan flies in with her pigtails. Notice the look on Osaka's face when she catches sight of Chiyo. :D
