Lone Gunman Games has posted up the entries for their sculpting contest where contestants had to come up with the upper half of these three-legged models.
From the post:
We had our first ever theminiaturespage.com community sculpting contest. Dan (Cacique Caribe) sculpted an interesting 3 legged bottom half to a 15MM miniatures and instead of finishing it himself wanted to donate it to the community to see how someone else would finish it. After many people held up there hands to volunteer we had them produced so that everyone would have something to work from. From the original eleven that said they wanted to enter we had 5 that sent in something and a lot of those who entered did so twice.
