    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.

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
