A Jellyfish Exhibiton in Hong Kong
Last January 20, 2008, a jellyfish exhibition was held at the Ocean Park aquarium-amusement complex in Hong Kong. The said exhibition showcased large variety of jellyfish, our boneless almost-all-water neighbor of the seas. Check out these great creatures:

Cool Optical Illusion by Bach & Hinton
If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. If you stare at the black + in the center, the moving dot turns to green. Now, concentrate on the lack + in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating if you’re lucky! It’s amazing how our brain works.

There really is no green dot, and the pink ones really don’t disappear. This should be proof enough, we don’t always see what we think we see.
