While looking up different art forms I found this one especially interesting. Here is a deffinition of ASCII art from www.walthowe.com/glossary/a.html :
"Artwork composed entirely of ASCII characters used as lines and shapes, not as characters with meanings. The simplest ASCII art is the simple smiley faces, but at the other end of the scale, they can be large, elaborate pictures. For a good collection of ASCII art, see the ASCII Dictionary."
