What sets it apart from the other free 3D packages is it's advanced features like animation, advanced rendering, and dynamic simulation. And, my personal opinion, it's fluid software is much more user friendly than Maya's.

The newest software to this site is Adobe Photoshop. Adobe Photoshop is a popular image editing and image creation software.
