Metaphor or simulation?

• It is difficult to find metaphors for processes, relationships, services, transformations.
• Metaphors tie our interfaces to mechanical age artifacts.
• MagicCap is a "metaphor" of a street, with different buildings offering services.

Whatever happened to the original meaning of metaphor? This is simulation!

Cooper is caught on the idea of visual metaphors -- or rather, visual simulation. But we do use metaphors for processes, services, and so on. (See Gerald Johnson)
