"A global variable is like your mother. She's there from the beginning. She'll always be Mom, even if she grows, shrinks, or otherwise changes. And while you don't call her often enough, sooner or later you'll need her and no one else can do."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
