Installing screensavers

I have seen some pictures of screen savers on flickr and they game me This link for it. It is a clock screen saver. I have downloaded and double clicked the .screensaver file but nothing seems to happen. How do I install it, is there a folder I should drag it to??

Drag the file into the Screen Savers folder, which is in the Library folder at the root of your hard disk ~/Library/Screen Savers.

it is installed

you just need to go to system preferences > Desktop & Screen Savers

and make the new screensaver active

i double clicked it but it was not showing in systems preff's. dragging the file into the screen saver /dir solved the problem though, thanks
