Before I read that the visual symbol was abstracted from a formula for equilibrium, I thought it looked like a stylized horse saddle, green on the top and orange on the bottom, or reverse, depending on whether you're looking in from left of center or right of center. An interesting optical illusion there.

Continuing the saddle analogy, my first thought when seeing the symbol was of a hyperbolic saddle, which has only one stable point if it's in a normal gravity field.
