I have been using fracture-FX for quite some time now. I was one of the original beta testers.
Over the past couple of weeks I have been helping them by creating some Key Features videos. If you are a keen FX artist and want to do some demolition in Maya you can get a demo of the plug-in here:http://www.fracture-fx.com/fracture_demo.
Quite a few of the videos are up :) there is still more to come so watch this space.
