Hey, grmmxi here with a different name. This colly was my first time doing ASCII art and AsciiArena site was and is a huge inspiration! I studied graphic design and I did my bacherlor's thesis about Amiga ASCII, which you can find here (only in Finnish): https://aaltodoc.aalto.fi/handle/123456789/16290 This colly was the production part of the thesis.
(And goto80 is correct, later on for my masters thesis project I created glyphdrawing.club which is inspired by text mode and old school ascii art editors. greets to all ASCII artists & pioneers! )
EDIT 2025: I translated the thesis to English: https://blog.glyphdrawing.club/amiga-ascii-art/
