Awesome, 3dee is really cool :) Performance isn't great but it works
nicely.

Why not leave qball in libgeometry?  Isn't it implicit that you'd be
using both libgeometry and mouse+keyboard with qball anyway?  If so,
imho it's fine.  libdraw et al aren't as cleanly delineated as they
could be, so these sorts of dependencies are common.

I'd personally be happy to see all of this part of the distro, it's
very interesting and throrougly in plan9 style, but it's just my
opinion (minus some of the model files of course).

Cheers,
