Jellyfish.

"Visitors observe the Amazing Jellies exhibit at the New England Aquarium in Boston, Massachusetts Monday, August 16, 2010."

The aquarium in Boston had a special Jellyfish exhibit up when some friends and I went yesterday. The jellyfish themselves were neat, but I was hypnotized by this fluorescent blue light that filled one of the tanks.

I could have stood in front of this window and watched people admire the creatures for hours. I was there for about 3 minutes and snapped off over 20 frames.
