"Think of how window blinds work. Hair with HIGH porosity is like fully opened window blinds. Hair with MEDIUM porosity is similar to partially open blinds. LOW porosity is like fully closed blinds."
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.
