- Collected here are 10 Java demos to illustrate various models discussed in our survey of cellular automaton shape theory. Click on the title above to read a web-based introduction, or download the entire manuscript (57 pp., 1.5 M) from our Research Papers archive. You may also download a more extensive collection of
17 WinCA demos (311 K) for use with our high-performance Windows-based CA software downloadable from the Kitchen Sink.
- For each of the Java demos below, load the approprite palette, birth and survival parameters, and initial image, as identified in the Table, then hit Start. All demos use the Box neighborhood; only #6 requires Free edge conditions.
