ISS

This International Space Station MOC by Lia Chan DFW is so brilliantly built I thought it was just a photograph at first. I've had the pleasure of watching this engineering wonder built live through many, many hours of streaming NASA feeds (space doesn't happen quickly, but always fascinatingly) and I sort of wish I could have been watching this MOC being built the same way. It measures over five feet long and is amazingly detailed. It's also up to date with the addition of BEAM and Cygnus-6, awesome.
