Clutter in software
I've spent a little time over the past week or so porting the software 3d engine I wrote in Java over to C, and I thought it'd be fun to get it working with Clutter... So I did :)
Note, it's very preliminary, but if you want to try it (to see if I'm lying, or to optimise my terribly slow and Java-like code), apply this patch to trunk and configure with --with-flavour=sogl-sdl.
