Nice effect! 22 FPS on my machine, in Firefox. Surprisingly, it runs much slower in Chrome and Edge (4 FPS)
u/sigveseb

Screeching by at 4FPS on my machine too :D nice mandelbrot though

Beautiful!
u/iverjo

Nice! Looks like it's a remix of https://www.dwitter.net/d/1231
u/Cistoran

It is! I'm new to the site and wasn't sure how to tag it as such. My apologies!
u/Xen

you can live edit the code of any dweet and a 'remix' button appears, click that and it posts with a link to the original ;-)
u/lionleaf

No worries, I've got you sorted ;-) Just make sure to use the remix feature next time. Nice remix, didn't immediately recognize it as such.
u/J2D28U

Damn... I'm new as well and this exchange has kept me here!
u/Xen

Delete the last 4 chars in the compressed string and watch the ball wobble around like mad
u/tomxor

Yeah -V/8 is for velocity damping on Y. Which is necessary with velocity based collision resolution. An alternative that doesn't require this is verlet integration, but that requires far more characters.
