  The visual effect highly depends on the framerate.
  In the Youtube video it runs at arround 70 fps.

  The heatmap movement is independend from the framerate.
  The actual scaling operation is not.

void noise_noise1() {

  CRGBPalette16 Pal( pit );

/* here is how the palette looks like:
DEFINE_GRADIENT_PALETTE( pit ) {
  0,     3,   3,   3,
  64,   13,   13, 255,  // blue
  128,   3,   3,   3,
  192, 255, 130,   3,   // orange
