Has there been any movement on Unity supporting Live Wallpapers, would love to use Unity for making some 3d live wallpapers but last time I looked it wasnt an option but with Unity 4.0 out I am hoping that maybe Unity could add a build option.
Actually I would also like to have this feature. Apparently there was a way back in 3.3 or 3.4 with a bit of hacking, not sure about 4.0. I guess the best bet would be to create a new feature request in the Feedback section of the community.
