If you've never been to the BioSphere in the outskirts of Tucson you really should check it out. As much as the original idea of the place never really come into fruition, there was a lot of really neat engineering that went into building the place.

The expand and contract as the air heats and cools, preventing all the glass windows from bursting from overpressure.
