Optical Illusions

Hey, just thought I'd post a few optical illusions:

<-- stare at the dot, for at least 20 seconds, and you'll see the shading start to disappear.

<-- Young lady...or old lady? (if you can't get it, I'll explain
in another post, later)












<-- woman or man?










Luv,
