Changing baground

[Omega Weapon]

Okay, so I'm not sure where to put this. But I was wondering if there was an add-on for vista/windows to change the background every selected period of time i.e 20 seconds, 40 seconds etc. I hope you understand what I'm trying to say.

Thank you good people of TFF.

There is a program called "Random BackGround", I stumbled on it earlier today, it will get the job done for you. Plus, it works on both Windows XP and Vista:

Random BackGround:
Version: 1.2
License: Free
Requirements: Windows 95/98/Me/NT/2000/XP/Vista
Limitations: No limitations

Publisher's description of Random BackGround
Random BackGround runs in your system tray, automatically changing your desktop wallpaper at a set interval. It can be configured to run automatically on startup, every set amount of minutes/seconds, or both. Additionally, double-clicking on the tray icon loads a new wallpaper instantly.
