elegant :)
u/keithclark

change S(i*.2)*i*q for S(i*t>>4)*i*q for varying firework effects (2 chars over the limit tho)
u/katkip

haha i like the variation
u/JWinslow23

If q will only ever be 0 or 1 (t%2), couldn't this just be for(x.fillRect(x.globalAlpha=.2,q=t%2,2e3,2e3),i=125;i--;x.clearRect(S(t|1)*760+S(i)*v+960,(q/2-C(i))*v+380,l=6-q*3,l))v=q*200-S(i*.2)*i*q? That way, the variation also works.
u/keithclark

I opted for what I had because it held the initial shape in the sky for longer before gravity takes hold. Your version works and if you're happy to trade off the initial shape, you could also drop the \2 and save another 2 chars
u/keithclark

... also q can be any value between 0 and 1
u/JWinslow23

Ah, my mistake, I forgot about floats
u/lionleaf

Nice one! #nye #fireworks

3... 2... 1... ignition... beautiful firework
