Bronze Spheric Theme is one of a series of sculptures of the same shape made by Naum Gabo over many years. This particular one will be on display at Tate St Ives until September 2011.
This sculpture is made of bronze and wood. Look at the different shapes within it. What does it look like to you? Does it look like it could move? How would it move? Could it be alive, or is it more like a machine?
