installing a screensaver

[Mason]

I am trying to figure out how to install a screensaver because I seem to have no idea how to do so. I downloaded the file and tried to set it up via the system preferences page. But when I try to choose the file, it shows up grey and won't let me select it. When I do a "get info" it says the file is a "unix executable file." I pretty much have no idea what to do, so any help is appreciated.

Thanks.

If it is a screen saver module for Mac OS X, it will be a file type .saver

If it isn't, it's not a Mac OS X screen saver module.

If it is, double-click it, and it'll ask you if you want to install for just you, (goes into user library), or all users (goes into system library, but requires a password).
