The Homestar lights up the night, um, ceiling

One of the lesser acknowledged varieties of pollution dealt with by us hermetic city dwellers (you know, besides the noise, smog, toxic, and cultural pollutions) is light, which is quite effective at disrupting animal mating rituals and stamping out the starry night skies alike. So mad props to Takayuki Ohira and his Homestar, which projects a star map with over 10,000 points onto whatever surface you've got—kind of like a janky version of the Zeiss Mark IX Star Projector as seen at planetariums the world over, except, you know, instead of being about $3.5 mil it's more like $350 US.
