Y’know, like the monochrome phosphor displays! The way the phosphors glow as a character fades away. Or when you turn out the lights in the room and the screen glows!
I big-hug-super-love the IBM Model M Keyboard. The classic buckling spring keyboard built to basically survive the apocalypse and fill the office with the sound of work: clickety clack!!! These nearly 30 year old input devices still rock and are revered for their tactile and audible response amongst
typists and programmers those with discerning taste in mechanical input devices. ^_^
