Michał Kaźmierczak has built several large dioramas, and they all keep getting bigger and better. His epic rendition of the volcanic world of Mustafar from Star Wars captures the fiery landscape and the realistic texture of the lava. The diorama rests on a footprint of 35 large gray baseplates. Here is a photo with the builder for perspective.

The microscale imperial shuttle in this photo really shows off the scale of this massive display.
