World Machine is an official sponsor of the NWDA & Planetside 2010 Animation Contest.

In short, the concept is to produce a storyboard of a short animation using Terragen (including the personal free edition). The winners get an impressive prize package, one of which is a copy of World Machine 2.2 Professional!
Check out more details at the link above. I will also be participating as a judge in the contest. The latest word is that it ends July 15th!
