Bristol Street Art

I was doing some Christmas shopping today and walked down Nelson Street in Bristol town centre which has some amazing street art all along it (Bristol is awesome for great street art!). Took a few pics (wish I had my Nikon with me!) and I like this one best... I blows my mind how these guys can make such smooth looking 3D art using spray cans! Genius! Not sure if this is who created the art, but its labelled 'Bristol Rodeo Rider 2012'.
