I am very proud that there is a dome theater right in our dear Pittsburgh. Tickets are very reasonably priced, less than regular theaters. Even though they mainly show documentaries, it is worth it for the experience. You will lose yourself and feel fully immersed in the splendid images. Trust me, it's better than 3D and no glasses needed.
I highly recommend seeing flicks with sceneries. I took my little 4 year-old cousin here to see "Flight of the Butterflies". At one point she was so into the movie that she stood up and reached out her arms trying to catch the butterflies. It was a beautiful sight. Thank you Omnimax for nurturing that childlike wonders.
