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.

  • SOURCE (189/140): s=40;for(W=c.width|=i=0;j=i%2,i<700;i++){r=s*Math.random()/8;a=s*(i%50-i%2);b=s*(i-i%50)/25;d=((a/W-.5+.2*C(t))**2+(b/W-.3+.2*S(t))**2)*15; x.fillRect(r*d+a,r*d+b,s*(.2+j*1.8),2*s-s*j*1.8)}

    i had to golf this code to get the original d/19898 under 140, but lost the "focal point" effect achieved here. In need of a shorter way to compute the (euclidean) distance from the focal point (defined by "d" in the code).

    please excuse my poor etiquette for i have now learned about code blocks and replacing EVAL with THROW to display compressed code, and the Discord for chat : )

    nice!
