Well, isn't north really about 340 to 020 degrees? Looks like if you threw
in a factor.

Here's a quick script I wrote for it:
$deg = $_GET['deg']; // get from URL, for testing atm
$deg %= 360; // make sure it doesn't break on eg 560 degrees
$deg = ((ceil(($deg-22.5)/45))*45+22.5); // break it up into parts we
know, there might be an easier way though, just too tired to see it.
