Isabella Blow

Muse of fashion designer Alexander McQueen and hat designer, Philip Treacy, Blow departed this life in 2007 aged 48.

This piece of art stands alone in a darkened room in the National Portrait Gallery in London. A sculpture by Tim Noble and Sue Webster it comprises taxidermy - a crow and a rat - fake moss, light projector and installation template.

It is fascinating, and asks questions of our perception of art, but I don't think I like it.

My extra is the daily Tai Chi session next to St Martins in the Field, near to Trafalgar Square, London.
