Back in '82 I wrote a little Vic-20 assembler that would write over the memory used by the font, so I could create tiles for video games. The first test I made was simply a picture of John Belushi from an "Animal House" still. I showed that at the local Commodore store, and they asked to use it for their display computers and asked me to present at their computer club. After the presentation, a few days later, I started to see all manner of nudes being created with my little program by quite a few people.
