Windows Vista and Windows 7 come with two nice screensavers by default, Mystify and Ribbons.  Both screens savers come as is and don’t have a setting button to modify the number of ribbons/lines or the width of the ribbon/line but as many sites point out you can modify a few system registry keys to be able to change different aspects of each screensaver.  Last year I wrote a couple of applications that will remove the difficulty and fear that some users might have with modifying registry settings into nice easy applications.  If you are curious as to what each screen saver looks like after the modification take a look at the screen shots from here.

Here is a screen shot from my the MystifySSConfig.exe config utility (the RibbonsSSConfig.exe look exactly the same).  The applications aren’t pretty looking but they gets the job done. There isn’t any installers, you just download and double click on the exes.  The apps are written in Autoit and the source is included.  Feel free to modify it as you wish and if you make any nice changes please let me know.
