works after hovering it

u/h3rmanj

probably don't work in older browsers either
u/BirdsTweetCodersDweet

It doesn't work till you hover on it, because v and y have no default values
u/BirdsTweetCodersDweet

c.width=568 t?0:(v=0,y=0) c.onmousemove=e=>{v=e.x,y=e.y} x.beginPath() for(i=88;i--;x.moveTo(300+S(t+i)*200,150+C(t)*C(i)*150),x.lineTo(v,y)) x.stroke() is too long, but fixes the hover issue - maybe you can golf it ;)
