Might be a bit of a minority opinion here, but I actually think the replacement for 67-2008's adjustable link made for a really cool linkage. The required placement for the link was in the middle of where the arm had to go through, so HOT used a unique combination of shapes and materials to make a "hollow" pivot point that was really cool.

I've always been envious of some designers' abilities to seemingly pull cool, complex linkages out of their heads and onto a robot. Does anybody have neat resources to learn more about synthesizing and designing linkages for various tasks? I'd love to learn more as that's essentially the most fascinating part of mechanical design for me right now.
