I really like it when someone takes a fig-scale MOC and builds a microscale version. One recent example is ThePaleMan's mini version of Chris Giddens' original PCS SLAM.
While we're on this topic, in his recently blogged Space Pirates Lair, Dennis Coh included a ship that Nannan Z (newest member of the Brothers-Brick team - Welcome to blogging, Nannan!) pointed out is a remake of Dennis' fig scale Izanami's Revenge.
One more - a couple of years ago John Langrish posted a mini version of Jon Palmer's M-Wing.
