I wrote a basic screen saver over the weekend called Sprial. To install it you just unzip the file and copy the "spiral.scr" file into your "c:\windows" folder and then select it your desktop properties. I'm trying a new file sharing service because my standby doesn't seem to be working. So you can download it here.
Leave me comments on what you think of the screen save and the file service.
BTW: Here's a picture of one of the runs. Colors and designs vary depending how long you let it run:
