I was on a similar kick* about 1.5 yrs ago. "Leaky Triangle" I could analogize everything (eventually) to a triangle that leaks "something" [because to even see it requires photons 'leaking' out].

Didn't abandon it but I knew I hit a point where I saw I wasn't "done" just yet. The symbol I ended up with is: > . < - but with the points of the > and < overlapping and a dot in the middle. == I found "the gap" to be something I'm always pursuing.
