For my art subject, I want to create a magic eye where you can see a logo I have designed. Does anybody know where I can download a magic eye creator that lets you incorperate your own designs into the magic eye?

Those are so cool!
Look at the bunch of software here (http://www.google.com/search?num=100&hl=en&lr=&newwindow=1&safe=off&q=%22magic+eye+software%22&btnG=Search).

If they do not work to your satisfaction, you'll also find folk who will make it for you for a fee, like here (http://www.magiceye.com/faq.htm).
