Finding similarities between how penguins huddle together for warmth and humans create giant crowded cities, artist David Graas created this complex lightbulb that looks like a tiny metropolis is exploding from its glowing core.
It was created using a 3D printer, and houses a modern 5-watt LED bulb so that it never gets hot enough to cause the miniature skyscrapers and apartment buildings to melt to the ground. It unfortunately doesn't look like it casts a tremendous amount of light. Which is too bad, because at least being a useful way to light a room would have made it easier to stomach its $US240+ price tag. Yep, almost a quarter of a grand for something you can barely read with.
