Dyson sphere lamp


In Dallas yesterday I saw these lamps which looked like Dyson spheres! I don't know if you can tell but it's a single light bulb surrounded by a shell of crossing thin strips of material. The most interesting thing about theoretical Dyson spheres is that they suggest we should not be looking towards stars for intelligent life. Sufficiently advanced civilizations would be harvesting and therefore hiding the stars they orbit!
