The pun game is strong with this one! What you're looking at is the evolution of scrollbars from 1988 to 2012. The title "The Elder Scrolls" brilliantly plays on the popular video game series while showcasing these ancient UI artifacts that younger devs might not even recognize.
Notice how scrollbars went from chunky, obvious controls to increasingly minimalist designs until they practically disappeared? That's modern UI for you—hiding functionality until users need a treasure map and three divination spells to figure out how to scroll down a page.
Remember when you could actually grab a scrollbar without pixel-perfect precision? Those were the days. Now we're all expected to have the fine motor control of a neurosurgeon just to navigate a webpage. Progress!
