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.
I like this #spiral and your code. A tip: you can remove "{" and "}" to save 2 characters. I also noticed that you have *64*1.5/32 that can be replaced by just "*3"
Nice! I didn't re-crush this one after changing some of the variables as I was still under the char limit. Excellent point about the brackets, I'll keep that in mind for the future.
