Subtle spiral with a square on the back… by rodrigo.siqueira

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

} // 122/140

    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.

Amazing how much a square can add to a piece.
u/erin

probably related to the 80/20 detail rule

gives more visual interest

Lovely, i agree there is something appealing about the aspect ratio of that rectangle
u/KilledByAPixel

because the contrast of organic and regular form
