I've seen a fair share of great lego creation websites, but Ken-Tucky's Lego Creations are absolutely amazing. His recreations of sets from movies and animation are just astounding. neomeds.net
For the anime geeks out there, he's made the bathouse from Spirited Away, the planes from Porco Rosso, the gunship from Nausicaa, and more.
Not to mention a ton of original ships, mecha, vehicles, and traditional pieces. I wish I could make lego sculptures as cool as this!
