Is there any interactive wallpapers like for example a background of a pond with some fishes and you could click on the fishes. I know this will consume a little more ram, cpu and video but it would look really nice.
I know there are slideshow wallpapers and wallpaper series that depend of the day of time, but in this case, wallpapers that the user can interact with.

Compiz does have interactive effects like water, writing in fire, and snow. If you have the graphics for it look into it- CompizFusion

Here they say there might be some for KDE, http://ubuntuforums.org/showthread.php?t=1073107&page=2
