@iain_bancarz I'dlove to see your paper. Trying to use up all my Penrose tiles, I get stuck and then I have to back up and redo part of it. Not clear on how radical a "back up" might potentially be required. 10 steps, 50, arbitrarily large? Consider problem of predicting whether a given Penrose tile configuration can be continued indefiinitely. Might this be computationally unsolvable in same sense as Turing's halting problem? #turingmachine #haltingproblem #penrosetiles #perplexingpoultry

#Penrosetiles #perplexingpoultry #freeware #wares. On a binge with a double set of these funny looking tiles. Non-periodic tiles ... tricky to make them all go in. Invented by the great mathematician Roger Penrose. I have 3D Perplexing Poultry in Chapter Three of my epic cyberpunk masterpiece FREEWARE. https://www.rudyrucker.com/wares/cc_downloads/html/#freeware
