Hello,
I adapted the famous Commodore 64 BASIC one-liner "10 PRINT CHR$(205.5+RND(1)); : GOTO 10" to the PICO-8 as a first learning experience. There are code snippets as comment available that you can copy to the prompt in interactive mode or run the program as you would normally and change the pattern in the pause menu. There is also a short blog entry available at my website, where I provide a link to the website hosting a free PDF version of an interesting book published by Nick Montfort et al. about this originally single line of code.
Have fun!
Michael

Would you be interested in doing a blog post for the PICO-8 subreddit on this cart? We're starting a weekly series (trying to) and this is an excellent first guest author cartridge, as it's not overly complex, does something cool, and teaches P8SCII, something a lot of people ignore.

I'm the moderator there (also the guy who runs unofficial API), so I'm not here looking to get free work from you - just letting you know!

Yes, sure. I just created the profile u/mickey_gamedev on reddit so you can contact me there to walk me through the process.

The PICO-8 character set has two more characters that are suitable for this kind of generator app. Their codes are 254 and 255, and here's how a pattern that uses these might look:

Very cool, thanks for sharing!
