The streets of Bristol are alive with Gromits! Eighty Gromits, to be exact. And they'll be there from July 1st to September 8th, 2013. Artists have been invited to have their way with Gromit, the Gromits have been placed around the city, and when it's all over, the Gromits will be auctioned off and the money donated to Wallace & Gromit's Grand Appeal, the Bristol Children's Hospital.
Here's a video of a Gromit being decorated by Simon Tofield, the creator of Simon's Cat.
