My dream machine was a room. There was a keyboard/display terminal, but also the program listing was shown (in that band-printer green/white perforated paper style) scrolled the floor where I could do a code walkthrough. There were also 3D pixelated models made in Lego fashion, one of which was a friend of mind Bill in half-scale. It wasn't apparent whether these things were physically implemented or VR--it was indistinguishable. I think I was walking around, either thinking about how to build something or debugging. Chances are that I was working on something that I'd left unsolved during the day that I considered challenging. I had this dream while I was in engineering in the mid-80s.
