John von Neumann's 29 state Cellular Automata Implemented in OpenLaszlo
Submitted by dhopkins on Sun, 2005-09-18 04:12.
For fun, and to learn OpenLaszlo, I implemented the classic 29 state self reproducing cellular automata, invented by John von Neumann.
The JavaScript and XML code is written with no thought to efficiency, just conceptual clarity and convenience of implementation. It can't run a lot of cells at once, but at least it's slow enough to watch it compute. Don't worry: there's not space for it to reproduce!
I've configured it with several interesting initial conditions, including several different approaches to signal crossing, and an exclusive-or gate.
It uses pie menus for editing the grid of cells.
