of course i didnt notice the fucking T-rex, it was hidden in a dark corner under a chair, not in the middle of the photo!  goddamn they think they are so clever.
They are actually very clever.  Even though I've seen the king kong one about 20 times, I always forget it's there and never take my eyes off the pretty lady.  That's not typical, most pictures people post or I see online, I've seen the whole picture within a few seconds...the pretty lady "optical illusion" pictures are the exception.  Within the first few seconds I'm still staring :x
