Love the animation!

Yeah, great communist BRONEVIK!

Nice.

Reminds me of Back To The Future, because of the folding wheels.

Can you build one for me?? :p
Nice smooth animation :) but I think it could be in low position longer..

Awesome work. Lovely style, works incredibly well with the palette with a wonderfully smooth animations. Superbly done.

The animation is really nice and smooth, fun to look at.

I think i remember this one, i like it.  Yes, a bump might help it, but i think its pretty neet as it is.  The only thing i would suggest would be a slight shine to some parts to reinforce the metalic idea, even painted trucks have a bit more shine than youve got at the moment

(just as a side note, all 'halftracks' have wheels on the front and tracks on the back, thats where the name comes from.  if theres a modern version without wheels and someone is calling it a halftrack, they are wrong)

this is nice thingy

Very nice, Brian.  Could use a few more animation details, but you got the main mechanical aspects perfect.

hoho cool idea ...

  I totally agree with you there sedgemonkey :).  By bounce do you mean like the truck is going over a bump in the road? That's what I would recomend.  Erm.., maybe some smoke coming out of the pipe thingy would look nice.  Looks great, keep it up :).

I forgot about that challenge. I'll have to go take a peak. 

The metal has a nice worn look and the animation looks tight -- very smooth. A little bounce might help a little to give it that "in motion" feel.
