SATX,
ASCII art is really fun... It's basically using computer symbols to make bigger images.
Here is some more fun info on it:
ASCII (ask'-ee) stands for "American Standard Code for Information Interchange."
ASCII covers letters, numbers, and certain control codes. It doesn't cover graphics. Essentially, ASCII artwork denotes artwork that is created without using graphics at all. Its palette is limited to the symbols and characters that you have available to you on your computer keyboard. It started back in the old days of computers. Most computers didn't even display graphics. So, people got creative with text and ASCII Artwork was born!
