Pink Bean - An in-depth look

They're numbered sequentially. Sometimes, though, an image has a pointer to another image saying, "Use this image instead of a new one in the sequence". It makes the program faster.

Also, all of the images are of variable size. They have to be centered and whatnot with different offsets than are given in the files (requires a mathematical transpose). I know all the math to do this myself, but so far every GIF animation I've ever made from Maple has been made by hand.

If you can do it, can't you write a program that does it?
If not, can you make a few teaser-animations? >

How do you get the off set value? o_0
