Well-said. And I think this is a good opportunity to remind people, especially users new to OSG, that they should familiarize themselves with OpenGL by obtaining either the Red Book (OpenGL Programming Guide) or the Blue Book (OpenGL Reference Manual). There are many other good OpenGL books available, and a quick search for "OpenGL" at amazon.com will list several. (Shameless plug: "OpenGL Distilled", for example.) OpenGL knowledge is really a prerequisite for using OSG.
