I've been pondering the earliest evolution of the nervous system,
and it struck me that the notion of _space_ must have emerged
gradually from a series of tropisms-- light, gravity, odor, wind,
etc.
To annotate this I first establish conventions for an organism
living under water:

Now I can tell some basic stories:

(The oppressor is standing on the oppressed.)
Now we introduce the tropisms:
