Try Droidz.org
A really good site to download stk figure. But you might need version 2.2.5 or 2.5 to open some files. I would really recommend for you to use version 2.5 (or 2.2.5)
because it opens almost every stk file on droidz.org.
Get:WWW.DROIDZ.ORG

pivot 3.0 is one of the newest animating programs for pivot. It allows you to use and create figures on hinges and change their colour or size. Another great thing about pivot 3.0 is that now you can add sprites(images that are GIF or BITMAP) I strongly recommend pivot 3.0
You can get a whole lot of stick figures, weapons, vehicles and backgrounds here!http:/droidz.org
