Tensegrity, or tensional integrity, is a construction principle where solid elements are held together by tension among cables. You may have seen the Needle Tower at the Smithsonian or this children's toy (my daughter had one of those as a baby). Or I remember building a floating flagpole when I was in the Scouts (that one's not ours, just one I found online). Anyway, there's been a spate of MOCs on Flickr in the last few days that use this idea to make it seem as if elements are magically floating in air. IMO one of the best is CaptainSmog's Invocation.
Esgyria, an elven sorceress invocating Tensegriton the mighty flying wyrm.
