    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.

Welcome Aoneill. Nice first Dweet! Here is a small change in your code to produce a higher resolution, just 127 bytes: c.width|=π=3.14;for(φ=0;φ<2*π;φ+=.01)z=f=>Math.abs(f(3*φ)/f(t))**f(t),r=99*(z(C)+z(S)),x.lineTo(962+r*C(φ),514-r*S(φ));x.fill()

Thanks Rodrigo! I was struggling to get it to 140. Didn't realize there was a ** operator in Javascript.

You've reached the end.
