Hi Guys,Lately I have been using Juice (a dynamics engine) to simulate the designs of the new creations I have been contemplating. I may not be super accurate, but it sure beats building something that doesn't quite work. Anyway I had a bit of spare time so I thought I would have a go at a Python simulation, and hay-presto it worked.
Juice is free to download from here http://www.natew.com/juice/ and Frank Bokhorst has a great resource page about it here http://wwwserver1.psy.uct.ac.za/juice/doc/juice.html -h
