As Cranmer says, he's spent a lot of time freelancing and working for various workshops and studios--forever adding more knowledge and ideas to the cabinet of curiosities inside his brainpan.
This LED sculpture of a giant water drop gives one idea of the sorts of projects to which he's lent a hand (the video is a must see--jump to 1:19 for the undulations). Cranmer clarifies his role in the making of this particular piece on his Web site:
"This was made for Roca's stand at the 2008 100% Design exhibition in Earls Court.
A large team of very talented engineers worked hard to make this--I played a small part by making a few components and helping with the general assembly. The sculpture was constructed at the workshop of 2D3D Ltd. in Park Royal."
