It may look like some kind of holographic AI, but this is actually Wikipedia's 100,000 most popular articles in 2014, mapped out as a galaxy.

The interactive visualizationā€”WikiGalaxyby Owen Cornecā€”imagines each of the 100,000 pages as a star. Related pages are clustered so as to be near to each other; pages of the same category all share the same color. There are even shooting stars zipping through the galaxy, which represent bots. You can zoom in, click around and generally immerse yourself in encyclopaedia. It's really rather fun to explore; check it out here. [WikiGalaxy via Popular Science]
