Not all in one place.

A number of people put their scenes on their own web pages and there are 
some impressive lanscapes and stuff. You might want to take a look through 
some of the stuff in the links collection at 
http://www.povray.org/resources/links/.

A few guys collaborated on a city generator last year which you should find 
on the povray.binaries.scene-files newsgroup. I recall that Mike Williams 
was one of the people working on that.

In POV-Stairs at http://www.geocities.com/povstairs/ there's the interior of 
a sort of hotel/conference/exhibition centre (shown in the bottom right 
illustration on the home page) that you could use for interior shots.

There was also a discussion about generating some standard country scenes to 
add to the POV-Ray object collection at http://lib.povray.org. There's 
nothing up there yet, but I've started working on a gulley with a river 
flowing down the middle of it. It's possible that the guy who suggested it 
is also working on that sort of generic background scene file.

Otherwise, it may be worth asking on povray.general if you want a particular 
environment to play with.

I've looked at a lot of that sort of material but I've never built it into a 
model.
Zeger Knaepen posted an animation in Jan 2006 with a very impressive upper 
body muscle configuration. See 
http://news.povray.org/povray.binaries.animations/thread/%3C43c6bed8%40news.povray.org%3E/?ttop=261005&toff=150

I'd recommend downloading and taking a look at the muscles2.m1v.mpg file 
attached to that posting. I don't recall seeing any advance on that since 
then though.

BTW, I also spotted my latest hair animations at 
http://news.povray.org/povray.binaries.animations/thread/%3C457d2bfb%40news.povray.org%3E/?ttop=261005&toff=50
while I was looking up the muscle link (a little bit of self-promotion).

Indeed. When you get to the face there's hundreds of muscles, so IMO 
emulating that in any sort of an authentic way would be very complicated. My 
thoughts on the animation of the face were to use sets of simple mesh 
deformations and to morph between them to get intermediary expressions.
