More moving structures

Nothing new here, just listing a few nice moving structures for the sake of inspiration.

Most interesting is the iris dome by Chuck Hoberman. This design seems complex, but it is based on a simple invention; a scissor mechanism with angulated members, so the angle of the elements the scissors connect to remains the same, which allows the structure to expand and collapse to and fro a central point, as in the iris dome. 

Here are a few interesting table designs. The last one is based on the Chebyshev walking mechanism.

Chebyshev walking mechanism, from "Sandler, B.Z. (1999). Robotics. Designing the Mechanisms for Automated Machinery":

What can I say about the following movies. I love these kind of Japanese comments, because not understanding them is ok; you understand what they're saying anyway because of the typical way they're saying it. This was never meant to become a very serious post.

The commercial partly shown at 0:14 of the following movie, about Hoberman's toy expandable spheres is one of my all time favourites. If anybody finds a link to the full movie, I'll post it on this blog.
