Totally heads-down at the Headlands.... Have decided the way you figure something out is to take a stab at the idea, and then experiment. Isn't that what scientists do? Hypothesis and then scientific method to test and compare results. Then test again and compare. I can't be sure what the pattern for self-tracking feels like until I just make more, and then more of them.
I'm in the midst of installing a huge room studio size piece at the Headlands Center for the Arts in Sausalito (more on this later, this place is fabulous).
With little distraction at night, have been pouring through books. Loved this one, 'Strangers to Ourselves: Discovering the Adaptive Unconscious" - which questions the notion of the other self, the one who controls our actions beneath conscious thought. Maybe self-tracking is a way to measure and watch the behavior of that other self. Philosophically, what if we're almost entirely controlled by our primal-subconscious .... the one that drives home without remembering anything.
The other books have been about non-western mathematics. Stay tuned.
