    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.

Nice blurring!
u/iverjo

I'm a newbie to dweets, but this is pretty nice. If you want to make it go slower, change t/2 to something like t/5
