Never personally, but I have to say, it's one of the things I miss from late 90's/early 00's internet. Heading over to GameFAQs (set as my homepage, of course) and looking up my favorite game to see some lovingly crafted ASCII fanart as the header. That's how you knew the guide was going to be good.

Six grade was when we learned to type in my school district. We didn't learn on computers though, but old typewriters. I remember if we got done with our lesson that day the teacher had these ASCII art sheets where you create art by typing. Each sheet had instructions on which keys to press and how many times.
I know it was tricking us to learn the keyboard and where keys were, but I really enjoyed making the typewriter art.
Making art with typewriters sounds really interesting! I've never heard of special instruction sheets like that before, and my searching just let me to a bunch of typewriter stock photos lol. Perhaps there's a specific name that'd make it show up, but either way I'm glad you were able to experience that!
