    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)

Superb! Golf the end with i*(t%2>1) or i*!(t&1)
u/rodrigo.siqueira

Thanks @joeytwiddle for the golf trick. i*(t&1) also works and it's even shorter. And I found that t%4>2?... can be converted to t&2?... It works as a counter to change the function each 2 seconds.
u/yonatan

Also, since T and S take the same arguments (t%4>2?T(b+t):S(b+t)) can be (t&2?T:S)(b+t)
u/lionleaf

Wow! Now we're talking

Wow, three fx in this tiny code? Great!
