zzBall Screensaver includes a mirrored ball that floats and reflects beautiful scenery.
zzBall comes in a zip file as a .scr, which is typical. Just right-click on zzBall.scr after extracting from the zip file and select "Install." You also have the option to configure your settings, which includes color schemes for the ball, antialiasing, background on/off, shadow on/off, surface effect for the ball (smooth or patterned), three sliders for reflection, speed, and transparency.
Since some people have asked about the author both here and on other websites, Javier is a regular visitor and indie developer who creates screensavers and small apps and makes them available to you on MajorGeeks. You may not have heard of Javier before, but MajorGeeks has always supported the smallest of developers since 2001. As always, all files on MajorGeeks are scanned, tested, and reviewed.
