What is the purpose of "encrypting" the co-ordinates? If it's to stop someone between the client and the server from seeing and/or intercepting the data, then we have something called "SSL" which is eminently suited to this task.

I don't recall you mentioning that earlier in the : thread. If you need to generate shapes on the fly, you'll need image : generation, which is usually non-trivial. : http://us2.php.net/manual/en/ref.image.php : : You might check out one of the image classes at phpclasses.org.
