Box2D has been officially ported to Blaze and is now availible in the trunk.

The main library is phobos/tango independent, although I am using Tango in the demos.

Project Page:
http://www.dsource.org/projects/blaze

Demo: http://svn.dsource.org/projects/blaze/downloads/blazeDemos.zip

So far I've only completed four of the Box2D demos, but if folks are interested in porting the remainder please let me know. It would be a great way to familirize yourself with the API and engine.

Have fun!

Best regards, Mason
