Fun with text: an image to html and an image to text converter. Back in the early eighties I ran The Electric Fence BBS (Rapid City, SD) using a commodore 64 and two, count them, two floppy drives. These were the kinds of images you'd find, using different shaped text characters to render the likeness of Farrah Fawcet or the Space Shuttle.
Of course you can only offer so many quaility downloads on two 170KB floppies, so downloaders left a message on the BBS and I'd load the appropriate floppy that night for them to download from.
