Enthought also has a units python module, which might be interesting to look at. It's not very well documented, though. > >> It seems that SAGE is also missing a geometry sketchpad component.

Do you know the license for k3dsurf? k3dsurf is a standard package that can be installed on ubuntu through the package manager. It is nice, but I think it's a kde thing, which would be a problem on Mac OSX, Windows, and other platforms we do or would like to support.
