"Phun is a free 2D physics sandbox!
http://phun.cs.umu.se/wiki/Phun
Phun is a Master of Science Thesis by Computing Science student Emil Ernerfeldt for supervisor Kenneth Bodin at VRLab, Umeå University. The solver is based on work by Claude Lacoursière
Phun is meant to be a playground where people can be creative. It can also be used as an educational tool to learn about physics concepts such as restitution and friction."
It's a very funny prog :)
There are some exporterters
http://phun.cs.umu.se/wiki/Links
I have use the Blender exporter, but Blender it self is not very easy to use!
It's will be cool that Moi has a direct exporter to Phun!
Curves must be plan and closed with no hole inside!
Why an exporter?
Because Phun as just "primitive" box, circle! But it can import any closed curves!
As Moi is very easy to use it will be easy to draw some numerous crazy things and play with them :)
for those you want use Blender : load the exporter and put it in the folders scripts
http://host-a.net/voormijke/blender_phun_export_script1.5.py
Load objects (from Moi) or create some curves
For kill the internal edges : Mode Edit: Ctrl + SHift + Alt + M = select outlined
Inverse selection : Erase edges : export the curve
launch Phun : load the curve and have fun :)
Why I don't use the Ai format from Moi to Blender ? Because I can't use it with success in Blender in first try, seems not adapted curves ;)
but may be I am wrong :)
You will find on Youtube a lot of examples of videos about Phun! Some basics but also some elaborated;)
All depend of the imagination of the creator :)
And all the scenes that you can load at this days 600 :)
