From wikipedia:
Blender is a free 3D graphics application that can be used for modeling, UV unwrapping, texturing, rigging, water and smoke simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications, including video games, animated film, or visual effects.
It wouldn't be a Slashdot book review unless it was cryptic about what was being reviewed.
