xvcoffee, There is a clip showing collision detection where a furry cloth square drops down onto a sphere and "pours off" or "drapes down" depending upon how stiff the fabric is. IIRC, the link to 2 motion clips is in the California Dreaming thread. We haven't had the program under our very own fingers to tweedle the knobs ourselves, but as Paula said in her interview, we have seen it on a laptop in real time. An hour isn't nearly long enough, though! I still have questions!!! Carolly
