I received the following via e-mail (from my boss ~ a really great guy!) a few weeks ago and just found it again ~ so bizarre I have to share.
This really works ~ what amazing brains, cognitive and visual systems we humans have!!!
Follow the following steps to discover an amazing image ~
1) Stare at the red dot on the girls nose for a full 30 seconds.
2) Turn your eyes to a plain surface on your wall or ceiling.
3) Blink repeatedly and quickly.
Isn’t that the coolest thing!!!
Have fun with this and of course pass it along.
What you should see is a full color representation of the image as your retina/brain processes the negative image. Our visual system is constantly processing input and can fool us or create illusions from retinal or cortical processes…
Please visit webvision.med for the full explanation of how the human visual system works in a case like this ~ most interesting!
