In 10's there was a lot of innovation with GUIs, incl. 3d interfaces (pre virtual reality era). File managers, document environments, really interesting stuff. Tons of demos, mockups, POCs. Even YT was full of these. All of this is gone and I can not dig up any of this. I still remember quite a few concrete demos. Also, lots of hardware, like touch tables. It all kind of disappeared, I dont get it where and how. (Enterprise?)
