A balloon universe in 3D ... as if our eyes were separated by the width of the universe (in stereo!).
Normally we see the night sky in 2D because our eyes are essentially located at the same position in space when compared to the size of the universe; our eyes are inches apart, compared to stars and galaxies, which are located lightyears away from us; From the universe's perspective, we are a dot, and from our perspective, the universe is ALL infinitely far away. Without help, we can't see any parallax in the night sky.
IF we could see the universe from a distance, and with eyes spaced the width of the universe apart, and if the galaxies were arranged along the surface of balloon shape, this is what we might see. In 2D you can't see the hollow center, unless you put it in motion (the rendered Quicktime is < 14MB); If limited to 2D, and if you studied it carefully, you might detect an increase in the number of galaxies around the edges. In 3D the effect is slightly better, but it is really good in 3D with motion, as if we were giants of the universe, space and time.

and you can see things on the micro scale here, as if our eyes were separated the same width as say an ant:
I would love to do a new "Powers of Ten" in 3D!
