My second attempt at Sierpiński's Trian… by Ohead

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.

if you don't mind cheating a bit =>for(X=2e3;!t&&X--;)//row for(Y=1024;Y--;)//col Y*2&X|| //if((Y*2&X)==0) x.fillRect(X+Y-64,1080-Y,1,1) //draw from bottom up

no comments => for(X=2e3;!t&&X--;)for(Y=1024;Y--;)Y*2&X||x.fillRect(X+Y-64,1080-Y,1,1)
