Well, they did work
Its true, the ilusions did work, I understand how the first one works, but it take a while to explain. though when i first tried it i did it wrong, held my mouse over the image, but I can see whe people say that there is colour there.
It would be coool though if you built this so that you can dynamicly load a picture with a given URL. Plus I didnt give you that high a score for graphics as all of those ilusions you took from othere places, your screen shots where of low quality and the look was a bit bland, but it dose not matter the much.
overall though this was a bit boring, just stuff to look at, would be better suited to jsut linking to the pictures in a forum post, but meh.
see if you can a huge collection and have a realy nice menu to navigate them, and maybe explain how they work.
