To use glow like I did, simply modify the code from the hack in the first post:

Find (in functions.php):

// ###################### Startdorainbow #######################
function dorainbow($code) {
  $len = strlen($code);
  $buffer = "<table><tr><td bgcolor=\"#000000\">";
  $mul = 255/$len;
  for($x = 0;$x < $len;$x++) {
    $color_h1 = 255*sin($x/($len/3));
    $color_h2 = $mul * $x;
    $color = sprintf("#FF%02X%02X", $color_h1, $color_h2);
    $buffer .= "<font color=\"$color\">";
    $buffer .= substr($code,$x,1);
    $buffer .= "</font>";
  }
    $buffer .= "</td></tr></table>";

  return($buffer);
}

And replace with:

// ###################### Startdorainbow #######################
function dorainbow($code) {
  $len = strlen($code);
  $buffer = "<table style=\"filter:glow(color=black, strength=2)\"><tr><td>";
  $mul = 255/$len;
  for($x = 0;$x < $len;$x++) {
    $color_h1 = 255*sin($x/($len/3));
    $color_h2 = $mul * $x;
    $color = sprintf("#FF%02X%02X", $color_h1, $color_h2);
    $buffer .= "<font color=\"$color\" face=\"Verdana\" size=2><b>";
    $buffer .= substr($code,$x,1);
    $buffer .= "</b></font>";
  }
    $buffer .= "</td></tr></table>";

  return($buffer);
}
