Peter Roesch has just contributed a set of stand-alone demos for the PyOpenGL-Demo distribution.  There's shaders, nurbs surfaces and curves, beziers, interaction and stereo rendering.  They should show up in the next release of the package, and are available from bzr now.

They'll also show up as example code in the documentation when I next update that.
