3-D Starmap Etched In Glass
I've always wanted to set up a computer desk to look like a pulp-era starship control panel. Needless to say, this will be an integral component for the navigation console.
Now I just need to rig a laser pointer that will move from star to star as a "position indicator".
Edit: Actually, I'd like to set up a computer/tv ROOM to look like a pulp-era starship BRIDGE, but I'd need a "Nav Cube" ten times the size...
