    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.

Huge improvement over my last Mandelbrot! I learned some tricks from y'all :D

Cool! You guys are making me addicted to this website. I'm new and still have to learn lot of the cool tricks. Nice to know about this "c.width|=", i'm still using a number to clean the canvas... :p
