The linked video shows my hackbaby of the last couple months, a hackable 3D compositing window manager written in Scheme. It's not much code, but it's rather fun. I'm still not dogfooding with it yet -- you can see a pause around minute 4:30 or so where I have to unstick keys that Xephyr thinks are pressed.

And it's still a bit hard to compile, because you need bzr guile-gnome, and the latest guile-clutter release, and a guile 1.8 compiled as --with-threads if you want the emacs integration. But if you want to join in on the fun, or read some interesting code, check:
