Examples

Sierpinski triangle

Command

/draw (x, y) => {
  const c = x & y ? 0 : 255;

  return {
    r: c,
    g: c,
    b: c
  }
}

Fancy sine

Command

/draw_center_hd (x, y) => {
  const val = Math.floor(Math.sin(x / 30) * 100);

  if (val < (y + 10) && val > (y - 10)) {
    return {
      r: x,
      g: y,
      b: x - y
    }
  }

  return {
    r: 255,
    g: 255,
    b: 255
  }
}
