A well-placed illusion

When I saw this sculpture by Chris Maddison, I didn’t think it was possible for all the pieces to be freestanding and connected. Even if supports were used, I couldn’t imagine how they could be Lego parts given the haphazard angles that the cubes were positioned. Even zooming on the photo and examining the gaps between the bricks revealed that each small cube is supposedly made out of a plain 2×2 brick sandwiched between a plate and tile. Just when I (and many others) thought the sculpture was impossible, Chris revealed the solution to this wonderful illusion.
