Libra - great listeners, the most balanced of all signs.
The only sign not represented by a human or animal, the libras are known for their appreciation of the little things in life and the people around them. They are very orderly and structure but that doesn't inhibit them for being very caring with the ones around them.
The logo was inspired on the symbols of the zodiac rather than their pictoral representation. The similarity with the equality sign is intentional for it represents the Libra's desire for equality and order in every satiation.
