Windows screensaver: how to?

Hi there,
I wanted to use my Windows “Desktop Aqua 3D Screensaver” in Linux too.
I just installed the screensaver using wine. Now the problem is that I would like my KDE screensaver to be a script that launches

wine /home/djechelon/.wine/drive_c/windows/system32/Destkop\ Aqua\ 3D\ Screensaver.scr /s
which worked fine from Konsole with fine OpenGL graphics and audio (I think I’ll report it to AppDB lol).

Any idea on how to do that? Hasn’t anyone ever created a configurable screensaver that launches a user-customized shell command? If I would like to create one, where can I find documentation on how to create screen savers in Linux?

Thank you in advance.
