This is the Constellation Mug available from Uncommon Goods ($13). When filled with a hot beverage (preferably lava), twelve different constellations are revealed in the stars. What's your favorite constellation? Mine's Orion. I especially like his belt. Because without it, Orion's Belt would be Orion's Penis, and there's no telling how many ancient sailors would have crashed their ships staring up at that monster in the middle of the night.
