Sounds good to me. I like making graphics routines so it'd be nice to convert some into a screensaver especially if it has a cross-platform audience and works equally well on all of them. I agree, screensavers have to be integrated such that they can update a preview window and also provide configuration options. I'm not quite sure though how you'd go about allowing a configuration option because usually this means setting up a real o/s GUI with controls.
