How-To:  Build A Reciprocal Roof

How-To: Build A Reciprocal Roof

Brian Liloia documented his build of this round self-supporting roof structure in 2008, while living in Missouri. This type of self-supporting structure, in which each beam bears the weight of another, and has its weight born by yet another, and all arranged such the load is thus distributed ’round in a continuous cycle, is called a reciprocal frame. It requires at least three members, and you can build a simple working model with matchsticks. [via No Tech Magazine]

And we can’t donate them to charity–the saddest kid in the world is one with a handheld video game that won’t turn on. Garbage, then? Not good for the environment. Luckily for us, there’s an entire class of scavengers out there ready to pick the bones of our helicopters, keyboards, and interactive t-shirts: hackers, makers, and crafty techy types.

They’re even polling interest in a possible subscription service. [Thanks, John!]
