    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.

u/Xen

very nicely
u/Toby

Lovely! How can you use r in the loop header without first defining it (done in the loop body)?
u/danny@hille.dk

Creative use of geme mechanics :-) The for loop has 3 sections separated with semicolons, first is for initializing: this is runs once before the loop starts, second is exit conditions: runs for every iteration before the "loop scope", third is for incrementation: this part actually first run after the loop scope. EX: for(i=9;i--;console.log(j))j=i*2 i is initalized to 9 i is decremented if i equals 0 (any number in js is evaluated to true except 0 wich is false) the loop exist then the j is set to two times i in "loop scope" finally j is printet to the console

This doesn't fit, but it compresses the lines so they don't overlap: x.lineWidth=s*s*(1+S(t)*S(i+.45)/2)
