Thanks! My brain is hurting right now, so it's not making much sense. But, I'll figure it out.

So nothing is invisible, hence this big image that looks exactly like the background. It is an "illusion" if you will. There is a great site to help you with this as far as static images go. The animation takes a bit more skills and, more to the point, tools.

Check both of these links.

Your profile is very cool! How do you make those invisible artwork pieces, so you can see your background through them? And, how do you make those animations? Is there an easy way, or do you have to be a smart person?
