I want to use SketchyPhysics, but it is not compatible with the newest version of SketchUp. I found SU 2014, and it works, but it only allows me a few hours "free trial period". How can I get SketchyPhysics to work with SU2015? If I can't, then how can I get (and keep using) SU2014? I can't seem to find it anywhere. Perhaps someone can post a link to download it? Perhaps there is another similar animation tool that I am unaware of? All I want to do is animate simple groups such as a rotating ceiling fan, or a door opening/closing. I am trying to design my house with lots of folding things such as fold-away tables and a murphy bed. You get the idea.

I like the concept, but it does not want to do what I am trying to do. I am trying to animate a folding staircase and a murphy bed. I got the starting and ending positions to work, but during the transition, the staircase floats off it's hinges and twirls around before settling back down to the second position. I just want a simple hinge. In OSX, is there a way to set the axes of rotation along the axis of the hinge? Imagine a basic door-I don't want the door to come out of the frame and place itself back in the open position-I just want it to open on the hinges! I can't find any way to set the axis of rotation on mac.
