Re: gwt-phys2d: 2D physics engine for GWT

I've put up a new version which allows one to use the mouse to draw as
many boxes as desired:

http://edgeofvision.com/tag/gwt-phys2d/
http://gwt-phys2d.appspot.com/

It definitely slows down quite a bit when you have many boxes, at
least on the netbook I'm using as a test platform. I'm fairly certain
this is due to absurd numbers of objects having to be garbage
collected every frame, which should be more-or-less straightforward to
fix.

I've also created a Google Code project and subversion repository:
http://code.google.com/p/gwt-phys2d/

Enjoy!
