    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

I wanted to make the trail fade away, but it only kinda worked, and I didn't have characters left for any relevant text.

had a quick play.... with(x)fillStyle=R(a=T(t+(h=560))*99,a/3,a,.05),font="9cm'",fillText(w=h*4,P=T(t)*9+h,P),fillStyle=R(h,h,h,4/h),fillRect(0,0,w,w)

almost kinda golfed it c.width|=p=3.14;with(x)fillRect(0,0,2e3,2e3),beginPath(strokeStyle="#90F"),lineWidth=L=200*S(t%p),arc(960,540,400*S(t%p/2)-L/2,0,7,0),stroke()

well, thanks

i could remove 2 characters from your golf and it still works(?)
u/Xen

120: with(x)lineWidth=L=200*S(t),fillRect(!beginPath(strokeStyle="#90F"),!arc(960,540,400*S(t%3)-L/2,0,7),2e3,2e3),stroke()
u/13thptr

u/doughno : must be blind, I don't see the difference
u/13thptr

u/Xen : nice but it isn't exactly the same
u/doughno

u/13thptr : i just removed the last argument of arc() lmao

You've reached the end.
