I found this at Grmmxi. A site from Heikki Lotvonen, a coder and designer specializing in modular design and text art. Then I found the Glyph Drawing Club which has a blog site to post about text art and a guide to using the GDC.
I had to change the code, the font I had typed in. Using FixedSys as the font had stopped working. Or, maybe it never did except for my own web browser. Anyway, the description for the ASCII Art category in the Curlie directory is showing ASCII art again (in the HTML). It works!
I found several (some I had not heard of before) books about and with typewriter art online, at the Internet Archive. They are a lot to look through and I’m glad someone else had the job of digitally preserving them, and I’m really glad they did!
