What a Great Observer I am

Recently I was stumbling upon ( surfing stumbleupon) and came across a site. This site has some pictures,some drawings. You have to carefully watch and tell how many faces/deers/animals can you see. In one picture if you find 5-6 faces you are average observer, 8-9 will be good observer and if you found all 11 you are extremely observant. And you guessed it right, I am extremely observant. unfortunately I didn't save the site, but I am on a look out and will post the link when I find it.
