This gorgeous building in France is more than just a pretty complex. The Cité du Design does one of the best jobs I've ever seen at concealing the solar panels that help power the structure.

The building is made up of 14,000 equilateral triangles. Some are solar panels, some are windows, others just fill out the structure. The net result is a building that manages to mask the black behemoths you're used to seeing.

I love how the exterior influences the interior lighting, not to mention how great it all looks when lit up. [Inhabitat]
