3d moving screensavers or non 3d moving screen saver, both are better than static pictures which are simply spread across your monitor. Anyway, screensavers were devised with the purpose of keeping the computer and the monitor alive and prevent the burn on the monitor out that happened if the system remained idle for a long stretch of time. So for these purposes, screensavers were designed as executable programs that kept the system in the working mode, even if you weren’t in the working mode.
Previously computer screens were black and white, with no colours splashed across the screen. The only purpose to use them then was that they reduced human effort or should i say multiplied human effort. One wasn’t really attracted towards it. Then came the era of monochrome screens which had graphics capability but only to the extent that all of it was green, black or white. People who are in their 40s will remember having seen that green dot blinking or the graphs or charts in only continuous green wave. This was the maximum we had in the name of graphics forget image consoles (icons) or 3d screensavers.
