A big hole mysteriously appeared recently along the Regent's Canal bikepath in Islington, North London. It's Joe Hill and Max Lowry's 3D street art, installed as part of a campaign to remind bikers to slow down.
I did a little research on 3D street art. Here's a collection of a few famous artists and their amazing body of work.
Edgar Mueller (German), Mysterious Cave, London Ice Age, Ireland Lava Burst, Germany Kurt Wenner (American) John Pugh (American) Julian Beever (English)
