Optical Illusion 3D Artwork
Look at a point in the center.
Just enough to prevent you from focusing.
Try to look 'through' the image without focusing.
Do not blink as you stare, let your vision blur.
The image will then become three dimensional and jump off your screen.
Persist and it will work for you!
If you can retain the illusion you can try to touch the designs that leaps from your screen...
its really cool! ; )
Penguins have an organ above their eyes that converts seawater to freshwater.
