Whilst browsing one of my favourite blogs 
http://www.polymerclaydaily.com/ I came across an exhibition advertised by an artist called Rachel Gourley - Core Sample opening next Thursday (unfortunately in Vancouver!) The exhibit features tall, hollow, organic forms created out of polymer clay.  She plays with form, surface colour, texture and pattern and combines these aspects with the challenge of architectural constuction. 
Polymerclaydaily says "..her colorful collection of self-supporting hollow polymer tubes stand 30″ tall looking like modern totems.

Rachel’s first explorations for this exhibit began when she developed back problems. Awaiting treatment, she would intently study the diagrams of the human spine in the offices of doctors and physiotherapists. Since then Rachel says, “I have thought a lot about the spinal column and how the body supports itself.”

Initially she titled the exhibition Vertical Vertebrae but she realized that the scope of her work had expanded beyond the human spinal column. She found herself investigating the structural core of organic forms and began to see parallels between spines, trees and columns in their ability to support a larger mass."

Personally I think they are fab!  Im on a mission and will post some more of her work when I find them!!
