One of the big things I still think about from when I did acid was the geometry. The normal popcorn pattern on the wall was replaced with a perfect diamond pattern on every part of it. You could write it out in a math equation or some sort. And why? Is the code that's the basis of our brain/eyesight mathematical? Is it God? There are certainly cases of it in nature, like snowflakes, leaves, etc. More loosely, the population of each city in a country tends to follow Zipf's law. What are your thoughts of why we see these kinds of patterns while under the influence of LSD?
