zzLines is a customizable, freeware retro screensaver that should seem familiar to many.

zzLines reminds us of the old lines screensaver from back in the XP and Windows 7 days.

There are a handful of options including Fade color, Use Curves, and Fade lines so that you can tweak this screensaver a bit to your own liking. You can even choose a background and line color by selecting a basic color or by typing in your own HTML or RGB code. Additionally, it now also allows you to add a curve or smoothing effects to the graphics.

Extract and right-click on zzLines.scr to install.
