Actually, I don't remember any more... I found those back when I was looking
for AT-AT pictures online to help with the details and saved 'em for
reference...

Yep, the one on my site is my 3rd, I'm now working on a 4th :)

I tried several techniques to make the feet as accurate as possible yet
still look curved. For a while I was using the 5x5 grey brackets (12 per
foot) and 3x3 brackets (4 per foot), but that looked a little too octagonal
for me, so I've modified the foot yet again... see
http://www.suave.net/~dave/atat/dat/ for DAT's on how I made my new foot
design... Shaun's foot design looks really great too.. I think it used 12
3x3 brackets? I forget...

Yeah, that was the hardest part for me-- figuring out how to get a system
that allowed for odd angles (as many as possible) and yet still be accurate,
look at least somewhat good, be as sturdy as possible, and not sacrifice
interior space...

That's been the thing that I'd most like to see of Shaun's design. I came up
with a few ways to do it, but none of them worked while still being poseable
(or I didn't have the parts), but Shaun's neck design was (by his account) a
latticework of technic beams with friction pegs such that if one moved, ALL
would have to move, and thus kept enough friction to support the head...
Not sure if it'd work with my larger head design, but I could never quite
figure out exactly how it worked to try... I have thought about trying a
flex system, however...

I'm almost sure that a minifig scale AT-AT made out of Lego could NOT walk
the way it's 'intended' to. The problem being that I estimated that you'd
need 7 different sets of pneumatic pumps, and 16 different timing mechanisms
tied into the 7 sets of pumps, since no other all-lego joint seems to be
capable of supporting the full weight of the body at the angles it needs
to... (that's without automating the ankle joints [ugh! just leave that to
gravity]) Although it may be possible without a detailed interior-- just
filled with motors/mindstorms bricks/motors/pistons/pumps, etc.
Anyway, it'd border on plain silly, I think... :(
