I know you know what screensavers are. Yeah I’m talking about those animated sequences that come up after your monitor has been left sitting for a specified amount of time. Any thing from different colors and designs that flash on and off the screen to slideshows of professional pictures or your own personal shots, to words and phrases, to animations like aquariums or video games. So why do they exist?
The original purpose for screensavers was more noble than purely entertainment. The fear and it was legitimate back then was the images if left static on the screen for too long would actually burn out or otherwise permanently change the actual physical units on the screen that the pixels corresponded to. Kind of like when you stare a something bright for too long and then wherever you look for the next little while you have an image, usually a different color “burned” into your field of vision. Its really annoying and actually ruined monitors. The idea was that if you had some sort of program that kept the images and background moving so that pixels weren’t left static on the screen you could avoid these image burns.
And it worked great...
