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.
You could use clipping to have the pointing hand disappear into the OK hand if you placed the clip rectangle just right. I don't know how you would save up the characters though, maybe by using a for loop to only have one fillText call (but that would also eat characters with all the ?: statements you'd have instead).
I posted a clipping remix. You can do scaling, translation and rotation in a single call to setTransform.
