Here are trophies from several past fests that use microscale to good effect.
From BrickCon 08, check out the best train trophy in the back left (anyone know the builder and winner?).
From BrickCon 07, see the best area layout trophy in the second row (again, could someone identify the builder and the winner?).
Aaron Sneary made these space trophies for either NWBrickCon 04 or 05. If someone knows who won these, Aaron would be interested in learning, as he was unable to attend.
