„Greebling“ is George Lucas’s term for the decoration of spacecraft models with showy, superfluous details – clumps of antennae, bulky rivets, bulging pipes, anything that whiffs of function. Speaking as the human grown from the ashes of a child who once built the Death Star out of LEGO, I do enjoy a good greeble now and then, but it very easily becomes a parody of itself – like turning a machine inside out, but none of the exposed parts are meaningfully connected. Liliana, founder of Eridanus Industries and lead developer of space tactics sim Nebulous: Fleet Command, has more practical objections to greebling, based on her eight years in the US Navy: excess surface details are an absolute dust trap for radar waves.
