ascii crawp

How would I "animate" large ascii art?

Lets say I use an ifstream to load the ascii art, from a file.
Then, how would I make the crawp "move", spin around, zoom in/out. You know, do stuff.

Take a look at: http://www.pouet.net/prod.php?which=5095

Any examples or theorys are welcome :)

well i guess youd have to create coordinate sets to make each letter,, then ue a rotation equation on each set, and output it to the screen
