Photographer Mike Balakov has recreated a number of classic photographs in Lego.

This is reminiscent of the Brick Testament, an extensive (4000 shots!) recreation of Bible scenes in Lego. My ten-year-old Ben is fascinated by these, and has been working on his own scenes from Greek mythology in Lego. It's a fun way to study the material, exercise your Lego creativity, and learn some more about photography at the same time.
