"Each chromatophore is like a plastic bag full of paint surrounded by a series of muscles"
"A chromatophore is like a flexible bag of color. It can be stretched out to cover a large flat area or retracted back to a small point."
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.
