Blender is an amazing piece of software.

A few years ago I asked myself "Why spend hundreds of hours sucking at video games when I could spend the same time sucking at Blender?"

Since then I have spent many an enjoyable evening making terrible 3d models, some of which actually made it into a game. Apart from my lack of skill, there is no reason why somebody like me can't do world-class renders in a piece of software they downloaded for free. It isn't even that hard to use any more.
