some of the most interesting chalk drawings by Edgar Müller. But this hasn’t stopped Edgar from doing some more excellent work, more precisely in Moscow, Russia.

Check out the concrete plaza in Moscow, before work on “Duality” has even started, as well as the finished product. More images after the jump.
