There is an image that I remember seeing, but that I have never been able to find. It shows 2-3 people on their hands and knees, crawling around a blueprint of a chip that had been rolled out over the floor of a room. Presumably this was from before computers had enough memory / processor power to supersede working with physical artifacts representing the design.
I'm probably mismembering the fine details (e.g. was it a CPU? how many people were there? did it actually cover the whole floor?).
Does anyone know the image I'm referring to, or have a link to it?
