This French gym is so bizarre looking, it might compel you to do a few laps out of curiosity. But it's also highly functional—enormous windows provide lighting during the day, with a solar panels juicing bulbs at night.

The attractive compound, designed by French architect Jean Marc Rivet, also features a rooftop garden, and interiors that are almost as attractive (if not as outright strange) as what's outside. [designboom]
