This is the Starry Lights lamp designed by Anna Farkas. It projects accurate constellations on the ceiling and comes in four different models (based on the way the stars appear during different seasons): vernal equinox, summer solstice, autumnal equinox and winter solstice. All the stars are as they appear at 45-degrees north latitude though so if you want some southern hemisphere shit you are OUT OF LUCK. Just kidding, they also make custom ones, it's just going to cost you. And considering they start at $1,000 it's probably smarter to pound some holes in a coffee can with a nail then dangle it over a bare bulb. That's what I did, and I think it turned out pretty good. See? There's the Big Dicker. "It's DIPPER." You sure? "Positive." This reminds me of the time I found up Alaska wasn't an island.
Thanks to Christian, who saved himself $990 and used a star map to put up a bunch of those glow-in-the-dark stickers on the ceiling the way we all did in high school and college. Hey baby, wanna see the stars? That was classic.
