Conway's Game of Life. I've always wanted to write one. Furthermore, I'm taking advantage of Touch Screen to edit the dots quickly and easily!

Sweet! Will I be able to see Langton's Ant (RLLR) and its highway at around step 11,000?

If you're thinking that this will fit in one screen, then you're right. At least the display part. What's that @SET label doing there? That's the editor. I usually use the #DOWN DPAD to activate.

Editor is kind of busy, isn't it? L/R for shifting display. X: Erase board. Y: Seed board. A: Display board. B: Exit editor. Have fun!

What's the difference between these two?

No difference! Well, one is a few steps behind than the other.

I don't think you want to run it to steps 11000. But sure, you can do all kinds of pattern with it.

Langston Ant March is different from John Conway Game of Life. Try looking it up. Gliders, Puffers, Oscillators.

Here is a simpler, cleaner version of @SET. By changing the loop to REPEAT-UNTIL, and switching things around a bit, I have a more streamlined code. I should've done this in the first place, of course.

make an HD version with the dot matrix characters!

HD version is not a good idea, simply because it makes the editor that much harder to use. However, you are free to modify this anyway you like. :)

this is the best pattern i can find

YES YES!!
