Not on Sunday specifically, but I dug out what I had, tidied up a few bits and have put the project onto Google Code. There's the library itself and a small test application I wrote that basically creates a small world, a plane and spawns spheres so you can see what's going on.
The bits that are wrapped so far are enough to get a world up and running and probably let you create planes, spheres, boxes and some joints, but you'll have to have a look at the C++/CLI code for the wrapper to work out whether the class/method you're after has been wrapped.
I suspect the way I'll work this is if people desperately want a certain bit wrapped or a certain method wrapped that I've not yet down, leave an issue on the tracker and I'll make it a priority. I'll try and keep working on this fairly regularly, but now I have a job it's going to be evenings and weekends only for now.
