GEOGRAPHY OF LIGHT

what is it? well, contrary to popular belief there is a plethora of answers, most of them confusing and none satisfying enough, methinx.
let's just consider several suggestions off the cuff.
- is it a candle 'burning bright in the shadows of the night'? well it is and of course it isn't. do u fancy open flame inside your hardware?
- sure, it is a snapshot of an object made of stearin (a glyceryl ester of stearic acid, derived from animal fats created as a byproduct of processing beef used as tallow in the manufacture of candles). well partly, as it is not a photograph;
- yes it is a sought-after artifact - oil on canvas by gerhard richter, or rather its representation on a computer screen as i still have to wake up in the middle of the night at the break of dawn to earn a living, so no it's not a richter at all;
- yes it is one ray of light (an idealised beam) after another leaving signals for the eye to detect them;
- it surely is a result of billions of actions taken unconsciously by somebody called me so that eventually i could realise i'm LOOKING AT SOMETHING and name the agent, the action, the object and the relationships within the holy trinity;
- it is a lie of the mind (Lie of the Mind - a brilliant collection of plays by Sam Shepard, a must);
- nothing is real everything is possible - William S. Burroughs;
... and it has only just started ...
