Very basic animation program, but still quite funny.

This program allows you to create simple frame-by-frame animations. There is a basic "onion-skin-like" mechanism and the linux modified version is able to export to mp4. However, this is more a game than a tool: there is no color, there are almost no options. The mouse is used almost only to draw (everything else is done with the keyboard).
