You can set each Space a different wallpaper.
You can add SpacesDecorator to your login items so that you can have it immediately ready once after opening your mac.
SpacesDecorator resides in the status bar and it does not take your Dock's space.
SpacesDecorator fades in and out your wallpapers when you switch Spaces.
One wallpaper for each Space, it is simply that easy!
More exciting features are coming too!
