Logic gates and origami? Professor Inna Zakharevich joined us to talk about Turing complete origami crease patterns. We started talking about Turing completeness which led to a Conway’s Game of Life-like 2D cellular automaton called Rule 110 (Wikipedia) which can be implemented with logic gates (AND, OR, NOT). These logic gates can be implemented a…
