Weird and wonderful at the 2011 Kinetica Art Fair

A futuristic zoo, an interactive sphere and a man with an ear growing out of his arm are all featured in the 2011 Kinetica Art Fair.

Now in its third year, Kinetica claims to be the UK's only art fair dedicated to robotic, new media, electronic, sound, light and time-based art.

This year's exhibition explores the evolution of the human body, brain, mind and consciousness.

BBC News visited the exhibition in central London to see some of the innovative and eccentric artworks on show.
