I made this crude flat-shaded head in a couple of- hmm hours? I didn't keep track of time :-P You can see the different triangulation resolution on his forehead and shoulder compared to the more detailed areas around his eyes (the triangles have disappeared in size). Anyway... It's a pretty cool tool! If you are a blender user doing sculpting I would really recommend you to try it out!
I found a build at GraphicAll.org
Hope everyone had an excellent summer. Thanks for reading! =)
