It is an assembly of spherical rhombus linkages that expands to form a semi-circular structure.

These models were built by Steve and Justin with guidance from Smitty. This is the six-bar linkage that guides a bottom drawer to a position that is level with the top ... http://mechanicaldesign101.com/2009/08/11/six-bar-linkage-prototypes/ Chris Longhurst has assembled a number of descriptive articles and illustrations about automotive engines, transmissions, steering, suspensions, brakes and tires on his site http://www.carbibles.com [caption id="attachment_442" align="aligncenter" width="300" caption="Automotive information"][/caption] Also information about roller coaster simulation software can be found on his personal website http://www.chris-longhurst.com/nolimits.html. http://mechanicaldesign101.com/2009/07/29/automotive-fundamental/ Mikhail Zhuk generated this animation of Jerome Choe's concept for a six-bar linkage that rotates a 70in TV monitor down from the ceiling around a virtual pivot positioned down from the ceiling and in front of the wall. We hope to build a physical prototype. (UCI Robotics and Automation ... http://mechanicaldesign101.com/2009/07/26/tv-deployment-linkage/ This video shows the operation of a cam-driven toy artist.
