Amazing how common/popular these games were 2,000 years ago. I like the transcription from a numerical/abstract space in your head into a 2D flat plane; a natural grid… It would be fun to do this with Fibonacci numbers; as a filter to analyze price movements to see what forms emerge; not to just let the price values hit an overlay of Fibonacci levels as is common now in technical analysis; but to allow the values themselves to unfold a form, as the values in a Palindrome create a form.
