I just saw this video on a bicycle that is being made with a tetrahedron design and absolutely think that this is cool. As a former bike racer and enthusiast, a light way and strong frame is definetetly an advantage. Plus, to be able to see through the frame through all those carbon fiber twists makes an attractive design.
I love incorporating really new ideas into my classroom to encourage creativity in students! Sharing fun new ideas such as a "see through" bike will help students see how people keep coming up with new ideas of better ways to do things.
In answer to the omni-present question "why do I have to learn this?" the answer is "because if you know something, someday, maybe you can be the creative brain behind ideas like this!"
