       | I remember in the original version you had all sorts of options,
       | and could even combine screensavers.
       | 
       | For people who may not remember: screensavers used to be a
       | neccessity as old CRT tubes would 'burn in' an image if they held
       | it static for too long - leaving a shadow of the static image
       | permanently. Screensavers kicked in after a few minutes and
       | displayed something dynamic so as to save your screen from burn
       | in.
       | 
       | In the 90's, having a cool custom screensaver was cool (around
       | the same time that having a custom ringtone on your 3210 was
       | cool), and you'd pay money for software like After Dark.

               | was such a powerful and rich culture that there was a lot
               | of writing, and a comparatively lot got saved for

               | A lot of software back then was open and didn't hide too
               | many of the details. Today, all the technical bits are

               | over. So much of the internet experience now is about
               | monetization. Even malware is about making money. You

               | It's not "true" burn-in (like CRTs or OLED) as it goes
               | away after a bit but it's fairly easy to trigger with the
               | current trend of very white/light grey designs in macOS,
               | the easiest way to notice it is move from a whitish area
               | to a mid grey one (Daring Fireball is a great example of
               | that problematic grey).
