ASCIIArtMaker

Description of ASCIIArtMaker program from Softdepia.com:

This little software is able to transform a JPEG or BMP file in a text file (that you can read with a text editor).
Pale and dark zones are replaced with thousands of ASCII chars. The result prints like with a pin printer ! It's an old souvenir from the eighties ;-) Fantastic for creating very light logos or funny e-mails signatures.

ASCIIArtMaker is a "Free to try" program. You can download and try it for an evaluation period.
