QuaDror - Because a Truss can make Tables *and* Buildings

You know what a truss is, right? No, thats tress, as in Goldilocks.  A truss, on the other hand, is basically a triangle, or a set of triangles, and is used in building out structures.
Why triangles?
Think of it this way - if you put together three sides to make a triangle, it doesn't matter how much you flex the triangle, the shape remains the same.  Oh, you can break the triangle, but short of that, its stable.  Put together four edges to make a rectangle, and you can mush it around and make it all rhomboid-y.
You see where this is going, right?  Make a structure out of triangles, and its pretty damn stable.  Enter trusses.

At this point, you're probably asking yourself - WTF?  Why do I care about Trusses?  I mean, I care, 'cos I live in a house which has trusses all around, but thats just about in the same way I care about the floor, y'know'what'i'mean?

Enter QuaDror, a wacky structure designed by Dror Benshetrit.  Its basically an L shape, with each edge cut to 15 degrees.  It turns out that when you put four of these together, you get a ridiculously stable structure, that naturally just kind of plops into stability.  Its kind of wacky to describe, but just take a look at this

Seriously crazy, and seriously stable.

Whats even cooler is that when you unplop it, it totally flattens, which means you can ship it easily.  Its The same basic structure can be used to make walls, tables, roofs, structural supports, basically anything that needs to be stable.  And, it just works.  Nifty!
