    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.

Replaced the dot with the "FOUR-PER-EM SPACE" unicode character #short #default #unicode

Oh, thanks

Isn't it even shorter without the second repeat call. I mean just adding the vertical parts inside the string

I actually realised this after 1 second from posting

Removed the second repeat call to make it shorter, as suggested by jylikangas. Used a bolder rectangle character, as suggested by joeytwiddle here: d/9591 #short #default #unicode

If you use 111111111 you get a 3D version with less bytes. :)

The graph r=theta spinning around the origin. 65 characters to play with, so there's lots of remixing potential. Try messing around with the trig functions, it leads to some fun results

Go fullscreen, stare at the center for 30 seconds, then look away from your screen (e.g. look at your keyboard). #opticalillusion
