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.

  • a #fractal #curve but I am not sure that curve is this because in the middle is different if(!t){a=X=Y=0;T=[0]};z=Math.PI/2;for(o of T)x.fillRect(508+X,508+Y,3,3),X+=C(a)*3,Y+=S(a)*3,a+=o==1?z:-z;if(T.length<8900)T.push(...T.reverse(),1)
