For anyone who is interested in movement, the use of the body and in dance, there is a fascinating Degas exhibition on at the Royal Academy of Arts. 

This exploration of Degas’ work looks deeper than the merely chocolate box images of ballet dancers with which he has tended to be associated in recent years. Early film and photographs such as the movement studies by Edweard Muybridge, which Degas may well have known, are also included in the exhibition.
