Blender is the open-source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. It is available for all major operating systems under the GNU General Public License.Mostly a bug-fixing release, but it also adds a few new features like subsurface scattering (SSS) support and two new composite nodes. Version 2.46 includes cloth and fur simulation, physics caching and baking, shading, glossy reflection and refraction, raytraced soft shadows, improved rendering features, and more.

I’ve just downloaded it a while ago, and i admit, i do not know how to use it. LOL.
Sad, I can’t put tutorials for it. So better explore it ourselves! haha.
