I just stumbled over this forum by accident. While I'm here, I 'll post a link to these videos, which I've been making since 2005 or so. The entries created in 2013 and later were created with Lightwave's implementation of Bullet Physics (Earlier videos were generated with the now-defunct Impact plugin).
