zzWay2 Screensaver features multi-colored lines randomly moving on a 3D grid - it reminds us of Tron's light cycles.
zzWay2 Screensaver comes in a zip file as a .scr, which is typical. Just right-click on zzWay2.scr after extracting from the zip file and select "Install." You can configure your settings, including color changes, line count, and rotation of the grid.
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.
