The zodiac is roughly two and a half thousand years old, which makes it one of humanity's longest-running systems for explaining why someone is like that. Babylonian astronomers divided the sky into twelve segments along the sun's path, and we've been assigning personality traits to them ever since.
Whether or not you believe any of it, the symbolism is beautifully designed. A ram, a bull, twins, a crab, a lion, a maiden, scales, a scorpion, an archer, a sea-goat, a water bearer and two fish — twelve images that stayed legible for millennia and still fit inside a small icon.
The staying power probably comes from the fact that people enjoy being described. Ask someone their sign and they'll tell you, then immediately tell you which parts of the description are wrong. That's a more engaging conversation than most.
This collection covers all twelve signs, using both the classic glyphs and the constellation patterns they're drawn from, in a palette that suits a dark desktop.
Pick your own sign, or pick the one you keep getting compared to. Either way your pointer gets a little celestial.
