I uploaded a subframe super fast ARAY bridge maker, but it's like the very basics of subframe :\ so IDK if that counts or not.
I have enough idea how subframe works that It makes me too lazy to go there......
I did get a rather pixelated prototype of an RGB doodle board working though: 2349441
*Groan* Iv'e never studied subframe tech so I have no idea at all how it works...
The problem is preventing spark crossover. When things are close enough to look good, they cross over, loop, and generally misbehave. Putting enough distance between components spoils the RGB effect. 'Tis a tough puzzle. Maybe subframe tech would help, but oh the tedious hours........
This is pretty nice! I think I might know of a way to implement RGB; You can use different colored powerable elements for starters, then have pscn with a different DTEC ctype for the red, green, and blue. And finally, for erase, just have one PSCN-DTEC that turns off the whole pixel. I'll start work on that soon!
