So I figured I should at least post something, and therefore I'll post, for now, others' LEGO work. There is an abundance of amazingly creative stuff out there, all user-imagined, designed and built. Below is one I just found recently. If you don't know what "steampunk" is, check out the steampunk Wikipedia page for a quickie intro. Note that other sort-of-related genres include "dieselpunk", "cuberpunk" and others.
The relevant Flickr webpage is here with lots of snapshots. Perhaps this isn't your particular taste, but I love this one. The overall look is fantastic ... and fantastical (one of those odd science fictional or fantasy-ish words). The design is absolutely unique. Check out the front of the hull. That large piece is upside-down. We have one; if I recall correctly it is from one of the LEGO Castle line of sets, the big bad guy ship. And he placed it upside-down! That is hard! In one of his comments he mentions that it was a challenge to go the SNOT route (LEGO fan terminology for building with the "studs not on top") and make the whole structure sturdy enough to keep itself together. And the details he put into the model as a whole are equally astounding.
So, it looks exceptionally cool and it was a challenge to build.
