Mathematics often seems more discovered than invented; we're simply stumbling over things in a Platonic realm. Are there interface ideas with a similarly Platonic character, not so much invented as discovered?

They often feel more contingent e.g. on our physiology, our culture, the nature of the information we prioritize representing. Things like rubber banding or pinch-to-zoom on a touch screen are so thumb-ish! But e.g. mutable linked representations are maybe more Platonic…
