    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.

Save a char by moving the fillRect call into the loop body to avoid ;
u/yonatan

you're right!
u/keithclark

I love this!
u/yonatan

it's also better to use rect height for the "alpha", avoids the jagged edges on the right. for(i=c.width=99;i--;)for(j=56;j--;)x.fillRect(i,j,1,(S(j*j+i/j-t*7)+C(j**5-i/j*6+t)**3)*j/99)

Could be your monitor is old, or your eyes
u/fujimotos

Oh hey, I can see the gray tails too. It appears when I don't focus on an individual node and try to watch the whole screen.
