Maybe I'm a sucker, being the son of an architect and all, but Iñaki Aliste Lizarralde's architectural renderings of famous fictional houses are awesome. There's tons of them on his Tumblr, but check out a few of the geekiest below:
The Simpsons House, Ground Floor
The House From Up
Big Bang Theory Apartment
Wait, they forgot the laboratory... Oh not THAT Dexter
For the Golden Girls house, Frasier's pad, and more, head on over to the Tumblr site. And fingers crossed Iñaki tackles spaceships next! Enterprise is easy, it's just two hallways and a deck.
