Title: crazy optical illusion.... Post by: zombie no.one on July 13, 2012, 05:13:50 PM expect a few of you will know this one, it's probably my favourite optical illusion

One I have sitting on my shelf to my right... http://www.youtube.com/watch?v=O1gXtzK15ME&feature=related Here's the printout. http://www.grand-illusions.com/opticalillusions/dragon_illusion/ (http://www.grand-illusions.com/opticalillusions/dragon_illusion/) The lighting has to be good, and closing one eye helps, but it is a pretty cool illusion in person.

here's another illusion I saw recently. very strange... (http://www.moillusions.com/wp-content/uploads/2012/01/Beyonce-Optical-Illusion.jpg) stare at the pic on the right for about 30-40 seconds, focusing on the red dot on her nose. then look at the white section and blink your eyes quickly a few times :smile: Title: Re: crazy optical illusion....

I remember this one from grade school....young or old woman? (http://1.bp.blogspot.com/_yTo-PPUo2YQ/TMFz-XgQSKI/AAAAAAAAAMc/Blvd0MhaYqE/s1600/illusion_Optical_illusions-s300x369-13681-580.jpg) |
