The doors of the Koenigsegg CCX open using the “dihedral synchro-helix door actuation” system. You can see this movement on the video
Cambridge University provides a useful overview of materials properties such as the chart below.

Joseph Klann provides a useful comparison of the leg designs for his Mondo Spider and Theo Jansen’s Strandbeest at the link:
This walking machine known as the Mondo Spider.
The leg of the mondo spider has the topology known as a Stephenson six-bar and is described in US Patent 6,260,862 awarded to Joseph Klann. Access it through the link:
Wikipedia calls this the Klann linkage described here:
Theo Jansen builds amazing walking machines.
Each leg is an eight-bar linkage. The Wolfram Demonstration Project models this linkage in a Mathematica notebook. See the link:
