The post title is a reference to MST3K, but the subject is LEGO. Some very nicely design projects I have come across:
"Memnonia" by Kernel
"F44-03" by Nathanael
"Herakles" by Jeff
and finally "Kalashnikov" by Leonard
Bravo, Gentlemen. You make me positively chatruse with envy, and you also give me heights to shoot for.
