I tried to render a circle,but got this texture instead

u/Joachim

Nice work! Have a look at this if you want a circle. Change M to change the render speed --> for(i=2e3;i--;x.fillRect(i,t*M,1,M))M=600,A=i-960,B=t*M-540,x.fillStyle=hsl(${S((A*A+B*B)/9999)*99},69%,69%)

I ran out of characters. But this is cool... i guess

u/13thptr

you can remove the brackets of the for loop, doing for(i=999;i--;) is 1 byte shorter over your approach and 1920 can be approximated with 2e3
u/mildlybean

thanks, ill keep that in mind for future dweets
