Awesome Illusions

[zippy117]

Post images of links to cool illusions you find on the web! Rules: Do not post images directly onto the thread, it would slow down the server, and more importantly you would all get baned. Here are a couple I found:
1) Album cover for Mind games, by John Lennon, turn it sideways and you see Yoko Ono's face in what at first appears to be a large mountain/rock formation http://www.bagism.com/img/albums/mind-games-cover.jpg
2) This image I made, find all seven birds (including the three in the foreground) http://2.bp.blogspot.com/_hg_-LE3ZAPE/SNA9Km9FfgI/AAAAAAAAAC4/BfvXxgCAQAo/s1600-h/clouds.jpg
