    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.

Down to 117, looks nicer on the canvas too... Still no room for typos though!

u/pavel

shouldnt they get thinner in the back, not wider?
u/pavel

Here is a rough starting point using real orthographic projection for(c.width|=i=9;i--;x.fillRect(960+2e3*S(a)/z-s/2,540+2e3*y/z-s*2,s,4*s))y=S(i+t*39)/99,z=3+C(a=i/8+t),s=99/z
u/BriSeven

they get thinner at the edges and shorter in the back. the fatter appearance is an optical illusion from the perspective
u/BriSeven

i imagine them as thin sheets of material rather than as cylinders.
u/BriSeven

it would probably look better if the front and back had the same aspect ratio but there’s only room for so many sine/cosine functions
