A whole discussion of this idea in the link.
"Ogres aren't the only ones who have layers. Chemists do too. This week I've been contemplating layers. Literally. I've been mixing my drug with octanol which makes it separate into 2 layers. (the rest of the details are irrelevant now but it's profound)."
Solution with layers? Italian dressing anyone.
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.
