I knew I had seen it somewhere, I am sort of surprised no one else commented that this is an old idea. Anyway, I liked how the site pixelates the images, at 0% they are completely unidentifiable, I checked some of the pictures that are already partially revealed and it seems to work fine. I noticed it is still in testnet mode, though. I also think it is a bit hard to find the images, the only way is through the small link at the bottom of the page?

Why is this in services if the OP is not paying for reviews or anything similar?, this should be in Project Development, IMO.
