Tore,
I'm sure you remember my attempts at the same thing.

Well, I finally decided that POV-Ray is the way to go. Yeah, harder at first,
but there are several people working on minifig walking includes (I've got my
own as well). After working with POV-Ray's splines, I am sold. What I think we
should be doing is working on POV-Ray includes.
And as far as working with the clock, there are many ways to make it easier,
like defining internal clocks that start and stop where you want (instead of 0
to 1).
Check out my tutorial:

I'm working on stuff every night. Many future animations coming!
I'm excited. But I might be just a bit over excited today because of the Mac
Mini and iPod Shuffle and other cool stuff announced today, so ignore my
excitement.
No really, I have been working on lots of animation stuff. VERY VERY COOL.
Here is a short preview (which isn't so cool but shows work being done).
