I was searching for DreamScenes over at DeviantART Gallery and found this Aurora wallpaper from OS X Leopard converted into a pretty neat DreamScene for Windows Vista. Its done using Adobe After Effects CS3 by ~filipe-ps.
So if you are bored with all the DreamScenes shipped by Microsoft, this one is surely worth trying out!
