CityzenKane, sometimes known as CZK, produces distinctive three-dimensional work from polymer clay. The walls of Spitalfields and Shoreditch are full of beautiful examples, often inspired by Asian or South American cultural references. We suspect our map below only scratches the surface (we've found other examples in Flickr, but have no idea where they are). So please point us towards other examples of work CZK in the comments.
You can also watch a pretty remarkable video of CZK putting one of his finest creations together on YouTube.
