Brilliant. Absolutely brilliant work.
SUBNORMALITY!
The comics on this site also has a lot of complexity that I'm sure you can admire as well.
Though sticking to the original topic, I do have an overactive mind. If I come across something that piques my interest, whether it be a topic, a problem, or even an anomaly that doesn't fit a pattern, I'll take it apart and study it for hours on end -- I'll even skip a meal or two if I don't rein it in. I oftentimes do lose sleep when I enter my near-infinite loops, and ambiguous problems are really a huge contributing factor behind my sleeplessness. When I tried pot in my late 20's, it did seem to quiet my mind (the repetitive music, or thoughts about mathematical proofs for example) at first, but it actually just adjusted the setting from spray to stream, which really wasn't a bad thing.
I can also relate to your love of nature, but not so much the metaphysical aspects. I was an organic farmer and an arborist when I was younger, and I do share a special connection with plant life. Though my relationship is more about setting in balance a complex system where I would monitor my soil, map the different types of soils in my area such as sandy loam or diablo series clay soils, monitoring both beneficial and harmful insects, attracting pollinators, and ensuring a healthy amount of biodiversity. Though, the way you feel toward rocks and plants, I feel toward machines, and they express themselves through their native mathematical tongue.
I don't really have an inner voice, so much as an inner child that I'm nurturing. Much of the time, my inner child will be a strong influence on my curiosity to learn new topics. It appears that what you have for Art, I have for Science, Technology, Engineering, and Mathematics. You have a wonderful gift.
