    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)

If you change some of the parameters, you could set it to 4 colors, but i didnt need to lol

You can save 2 characters if you remove 2 first lines of code and start with: t?x.fillRect(y++%16..... and end with: .../2):(y=0,c.width=40)

Play around with the '6' in i=t*6... Fractional values such as 5.125 also work well :D

If the image is tilted and you want to straighten it, just make it t*{something}+{a decimal value you'll have to use trial-and-error for}
