Has anyone done any systematic evaluation of ways in which Turing Tumble is computer-like? It seems there is more than one analogy and different interpretations of the role of the balls. For logic gates the balls seem like a clock pulse generator. For most of the puzzles in the book the clock aspect seems almost incidental and the puzzles relate to counting/ sequencing balls. “Outputs” can be interpreted from sequences of ball colours or from position of bits and gear bits. “Inputs” can be position of bits and gear bits, numbers of balls, lever to pull and even orientation of the green levers. Has there been any posts that systematically lay out the possibilities and what each approach is good for?
There are some articles.
