Blender 2.72b

Being a professional, free, and open source application for 3D graphics creation, Blender is unique because it is free and open source. What is even more surprising is how well the application is developed. It has a user interface that is screaming quality and efficiency that complements all of the features that come with it. Why pay for software when you can get something just as good, Blender, for free? Also, being open source also means there are frequent updates and added features that will keep you using the software for quite some time. 

The software can do a lot in the way of 3D graphics creation. You can use Blender for creating animated films, 3D models, interactive 3D applications, and even video games! With a lot of flexibility to open up your mind of creativity, Blender offers as many features as you would expect of expensive, paid software - but for free! This gives users even more incentive to continue using the software. It also is one of the reasons why it has a pretty decent sized community backing its open source project.

Starting out back in 1995, the software continues to recent frequent updates and search its community with more and more features to open up their creativity. The interface is clean, efficient, and everything seems easy to find when you need it. It also looks of quality, but that is just a part of it. The quality really shines when you start modeling and creating.

Blender is also multi-platform, which includes full support for Microsoft Windows and all of its new versions that have been released, and future versions as well.
