here's a little one i wrote last month... it's pretty basic. If you want to make your own animation, use the header file for reference

/*
ascii animated video program
To create an AAV, simply create a text file with the following format
3 <--- height of current frame
000   \
000    |---content of frame (doesn't matter how wide, as long as it's the same hight as specified
000   /
1 <--- how long the frame lasts in seconds (can be a decimal value, e.g 0.04 is 1/25th of a second

just keep on adding sections like this to build it up frame by frame
enjoy!
