In other words... a meatspace debugger? Cool idea, but I don't quite buy the comparison to "spaces laden with sensors and visualizations" like the NASA control center, Large Hadron Collider, etc.. All of those spaces revolve around monitoring, not the design/making process. In a similar vein, in my field of computational science, heaps of money has been invested in spaces for data exploration/visualization [1], unfortunately, they are essentially useless for the scientific process.
