Francesco: Nicely done, the effect works very well. It may be all from existing ideas but you brought them together very nicely, implemented them superbly, and explained the method clearly, so all can learn from it. Take the credit, you deserve it mate!
Steve: Never underestimate the power of a work-around! Obviously there is still a lot of functionality that could be added to Anim8or (and no doubt will be in time) and animatable materials would be great, but figuring out work-arounds is good exercise for the old grey matter, and is (in my opinion at least) half the fun of Anim8ing! Clicking on a button that takes care of things like IK, physics, particle effects, animatable materials etc. is almost too easy and takes away somewhat from the skill of the modeller/animator. That's not to say Anim8or should not receive the benefit of these functions eventually, just that it is already way powerful enough to keep us pretty occupied for the moment, and Francesco's work above is evidence that where there is a will, there is a way.
