This is a reimplementation of a little graphic demo I first saw in the early 90ies on an Amiga500.
I have been writing that kind of demo on pretty much every platform I ever coded with since then.
Was good to see that something like that is possible on pico8 as well. Funnily enough, I pretty much ran into the same bugs, colour mixing issues and performance bottle necks as any other time I wrote a bouncy ball.
Enjoy!
Ha, lovely. Though to really get the Amiga Boing going we need some lateral movement and Jesu Joy of Man's Desiring going in the background.
(I spent ten minutes hacking in a very sketchy shotgun blast of oscillating x offset functionality but it was based on a sufficiently shallow read of the code that I wasn't able to get the per-frame cleanup working totally correctly. But seems like it's probably trivially doable with a little more knowhow.)
And looking at that again, I'm realize I mashed up the Boing demo (with its echo bouncing and no music) with another Workbench demo that did some fancy line cross-hatching patterns while playing Jesu.
