Extremely Detailed Drawings of Cities- Ben Sack

Benjamin Sack is an artist based in Virginia.  He creates massive drawings with insane detail, mixing details of past, present and future cities around the world.  I want to find where he exhibits because one could spend hours examining each section with a magnifying glass.  He probably can't upload ultra high res imagery without fear of people stealing the work, but it would be amazing to pull them up on a big screen and explore, much like a Google map.
