Sneer all you want, gents, but with advances in composite construction, it's inevitable that aircraft will take on more organic shapes. They're more efficient for moving through fluids (like air), it's pretty obvious.
Almost all previous design shapes are the result of compromise, where things have to be framed and put together a certain way, and weight looms over the whole equation, causing yet more compromises.
I can't say I like all of them, but that second one (the small model) is just beautiful. And that huge flying boat or whatever it is... I kinda like it.
