The Webinar on Celullar Automata of Toothpicks took place on Thursday, November 17th, 2022 from 4 pm until 5 pm with Omar E. Pol, Associate Editor of the Online Encyclopedia of Whole Number Sequences, as our invited speaker. This virtual event was free and open to the general public.
The invited speaker explained that cellular automata are like animated drawings that start for example with a simple small square, or with a line, on a grid sheet and keep on growing following a very simple rule. Omar E. Pol then described that cellular automata of toothpicks differ from classical cellular automata in that they are formed by lines instead of cells and that as they grow, they form different polygons and also geometric figures based on quarters of circles. Omar E. Pol also showed multiple examples of cellular automata formed with toothpicks that create astonishing artistic designs and invited the participants to continue exploring them in the link oeis.org/A139250/a139250.anim.html.
