Wallsaver 2.5

Wallsaver is a clean and simple application that lets you run pretty much any screen saver as your desktop wallpaper.

Apple has already perfected a screen saver engine, so we saw no point in wasting time trying to write our own. Wallsaver focuses on ease of use and a clean interface.
Wallsaver automatically searches the three directories your Mac stores its screen savers in. Just open Wallsaver and you're ready to go. Drag and drop any screen saver into any of the directories, and Wallsaver can use it.
Wallsaver features full Front Row support, screen locking, and even lets you choose a screen saver different from the one set in System Preferences.
