This one is courtesy of Rainer (tinhead). It is a farily simple 2d simulation program for experimenting with pendulums, springs, joints, hinges, and various other parts and components. Lot's of fun!
It has a pretty good little tutorial that I highly recommend. I tried it out and was able to do some VERY simple things. I got the idea that as you get more advanced, the learning curve gets steep in a hurry.
But all in all, a great tool and a great addition for the community. Thanks Rainer!
Here is the website where you can read about and download the program:
