A Czech Republic based architect firm has created this prototype of a bike sauna to experiment with ideas that also act as social tools. And as we all know, the best way to get social is to strip half-naked, climb into a vaginally inspired shape made of space age materials then beat each other with various flora while sweating your ass off.

Here’s the thing…this sounds absurd now, but re-read this post in a couple months when you’re biking to work through knee deep slush and into a sub zero wind chill, THEN tell me how ridiculous this was to create.

If you’re curious about the specifics, the sauna holds up to six people and is heated by an internal fireplace.
