Meshmixer is one of the more interesting free (although not open source) 3D apps.

Enjoy!
I'm still trying to figure out if this will give me any benefit or if it's just another program to get in the way ... looks fun to play with though.
I think maybe MeshMixer now (in it's current state, get me right, please) is a very good way to invite new users to Blender Community. It's much easier... looks just like a toy. And starting from toys and games the new beginning should be :)
I just recently got interested in Meshmixer since I have been experimenting with a Makerbot 3D printer. It looks like it has some neat features for hobbyists and more advanced users.
Ok, some features look like they could be interesting... but for me personally, overall not compelling enough to start messing around with it. If those features could somehow make it to Blender... that would be great of course.
