I was trolling the forums @ digitalpoint.com today and I came across a web site that I would like to promote.  It’s a new web site full of optical illusion photos and drawings.  They even just added an upload page, so that you can add your favorite optical illusions!  I must say though, there is a good chance it is already featured there.

Give it a try, www.visualfunhouse.com is the address of the web site.
