I saw "Deep Sea 3D" at IMAX last night...
I took my two daughters to see the movie and it was amazing. The visiuals were unbelivable, you truly felt like you were underwater watcing the interaction of the animals. Although I don't have a saltwater tank, I now want to get one set up as soon a possible.
The diffent types of ecosystems in the ocean were very interesting to see and they showed a full grown pistol shrimp (12+ in)...now I know why these this are such a nuisance.
If you have the opportunity check it out
