Forth invented as a monitor and control system for one of the radio telescopes at NRAO in West Virginia...<p>So I have a tribal affinity for Color Forth, by original creator of Forth.

Very impressive demos! I did a quick look through the docs- it’s single threaded (in the cpu sense) and not multi process yes?

In the first code example in the readme ("First program"), there's `sdlcls`, `SDLinit`, and `SDLShow`. Is there some significance to the capitalisation?

  r3forth is case insensitive

    Ah, it might be nice to mention that before the first code example, then. Or just use consistent case in the first example, to avoid distracting people with details that aren't the thing you're trying to demonstrate.

Very nice graphics using SDL2!<p>So many features-- sprite sheets, etc. Well done!

Very interesting, great work! This reminded me of something. I just checked and to my amazement Mike Hore's Powermops is still around and even has an ARM version.[1]<p>[1] <a href="https://www.powermops.org" rel="nofollow">https://www.powermops.org</a>

  Yes, that's neat -- it is basically a modern Neon, which was an object-oriented Forth for the Mac in the 1980s.
