Spent the last few days putting together a new Live Wallpaper called Galactic Core! I spent a fair bit of time trying to port over my OpenGL stuff written for Synergy before coming across Robert Green's GLWallpaperService example, which made life much easier. All my TextureManager, MeshManager, Timer, etc code more or less dropped right in once I switched over to it.
The end result is a very pretty (in my opinion) rotating spiral galaxy with multiple layers of rotation moving at different speeds and scales. It seems to work well so I'm tossing it out into the wild. I've got plans for some other wallpapers along these lines -- very attractive background images with motion added -- for the next week or two. We'll see how the feedback goes, hopefully people will let me know if there's any issues.
