<puzzled look>  A flock of geese, a herd of horses, a murder of crows...I
suspect it isn't *that* revolutionary, though it is in some sense neat.
You could consider things like "flocks" and "herds" isomorphic to
integral, independent vector subspaces.
In your example, any vector space isomorphic to the complex plane, like
Euclidean two-space, would do just fine.  :-p

And what does it mean to "understand" negative numbers?  Or to
"understand" complex numbers?  This isn't a trivial question!  <G>

And in physics, negative acceleration = deceleration.
