LEGO Asgard Mothership from Stargate SG-1
OMG this lego Asgard Mothership rules!!! I'm so glad they left other objects in the picture so we can really get a good impression it's size. For the geeks out there like me this is the Beliskner, Thor's mothership. Wikipedia also has two great related articles: Stargate Ships, and Earth Starships. There you go more ideas for more really cool Lego Starship designs.
