I'm after making a 3d Screen Saver (again)

I want to be able to make my models up in lightwave, give them some cyclic behavoirs, and drop them into a screen saver program so I can show my model rotating, moving and generally being fantastic.
Most 3d software uses OpenGL or ActiveX to display the models and so do most screen savers so I would have thought it would have been a relatively simple task (and one that dev's would have made an app for) but I cant find any software, links or tutorials. Most posts I've found say this is a "programming task ..." but surely someone would have seen the gap in the market and made an app ...
Suggestions on a postcard please
