a poem in the link...
"A freight train is like 100 or more semis all drafting each other about 3 feet apart. They only have one frontal area to push through the air."
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.
