Felicity/Team,

This is the website where i found the 3 different structures:
http://www.oobject.com/category/wonderful-tensegrity-structures/

And this is the website for the tensegrity lamp is:
http://www.christian-alexy.net/tensegrity-strukture.html
Its in german though so just go google translate and translate the page.
Something interesting about this is that the actual lights were strong enough to bear the weight of the structure.

Im going to try source those three pronged clip thingies that this german team have used as joints! As they conduct electricity aswell as act as a solid connection.
