I agree, it would be much cooler to 3D print it, using the image as a heightmap. Maybe even make 4 separate pieces to increase scale. Preferably in a FOSS 3D printer using home-made plastic, with the models uploaded from a PDP-11 only using the shell.
I agree, but I think it would almost as cool to reproduce the 3D model in Minecraft, hire people to keep it up-to-date in real time, and then project that into your room. Or maybe a stadium.
