Demo of some 'higher order' uses of roons[0]

Combine with tromp binary calculus[1][5] to demo 'free variable' as marble loop hole / 'jiggle' factor / statistical variance. (vs. original Lord Kelvin tide predicting machine)

Suppose would be bit tricky to orient pacman, even if for 1d roon pacman[3]. Roon pong version of [4] including 'roon marble matrix video'? Although, robotic pic-n-place / mechanical assembler for roon circuit assembly might make things bit easier. aka hardware implimentation of lisp.

Would be interesting to see an 80's 8bit computer (c64/atari) implimented in roon logic with LLM[2] to see how AI gets the proverbial ball rolling to arrive at a solultion(s).
