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.

  • f8f82804: This is the best solution I found to having them not be too fast; we only change the pattern 7 times a second. Using S() means there are occasional patterns in the drops. Change to y=99*Math.random() to see the difference.
  • f8f82804: also see d/9803
  • donbright: hee hee, thanks
