 Phase portrait gallery

A 'phase portrait' is not a portrait of a person.
A phase portrait is a portrait of  a state.
In the situation above, a phase portrait is the portrait of a state that is the outcome of a sequence of actions.

Every action sequence stopped more or less before any next action would overwrite a previous action,
 i.e. every action sequence stopped before it erased parts of its own memory.
