Great!
u/@noel

u/magna Thanks, but I made it on a slow PC, now that I'm watching this at home it's way too fast. Is there a way to handle this in code?
u/vain

@noel:

@noel: i'm not really sure. But i think the best way to get it work same speed on all PCs it to use t (timer). Btw, the function u(t){your code} will be called 60 times per second. So using d-=4 should run same speed on all fast PCs - but slow down on older slower PCs.
u/vain

Btw, it looks really cool with this green shining spikes.
u/joeytwiddle

I like it, running fast or slow! Viewers can always add t/=2;
