Cellsprings Help: Other Web-based Resources

Isle Ex, my website, has a lot of material related to CAs that serves to supplement these help documents. The most relevant pages are listed below.
CA Music Background Information
Contains an overview on CAs and CA terms which, as the title implies, had its origin in the context of my CA music exhibit (before I'd done any Java stuff). It is recommended, though, because it introduces CAs in a way that helps you grok the quirky Cellsprings slant on the subject.
Cellular Automaton Music
The headquarters for my "big" innovation related to CAs, viz., musifying their demographics.
As for non-Isle Ex resources, I've gathered a few excellent links below, though some of the annotations are a bit dated. (The list was migrated from one in the WebsideCA docs, receiving only a partial update in the process.) When I find time I'll update the text further, but I make no pretense of staying abreast of the Web CA scene. Thankfully, though, a couple of these sites themselves do a good job of that.
Exploring Emergence
Mitchel Resnick and Brian Silverman (the discoverer of the immortal Brain rule) have created an excellent Java-based active essay on complexity concepts, which uses several CA rules for illustration. Highly recommended as an accessible hands-on way to quickly build the conceptual background for getting more out of Cellsprings. If you're new to CAs, this should be the first place you visit.
Mirek's Cellebration
In the last year Mirek Wójtowicz has produced some unparalleled Web resources for CA exploration, including an extensive rule catalogue and a corresponding gallery of representative states. To top it off, Mirek has recently written MJCell, an applet that runs the same rules and patterns as his excellent Win32 program MCell. Mirek also has other sections devoted to sampling the latest and greatest happenings on the CA programming front. In my rule and seed comments you'll find many references to Mirek and MCell, and for good reason.
Alan Hensel's Life applet
For Conway's Life exploration, the conventional wisdom is "the bigger and faster the better". And here's the biggest and the fastest kid on the block, hands down. It's fitted with a rich assortment of cell-patterns, and, though it's geared to Life, it will also run most other rules of the standard Moore OT persuasion. Very impressive.
CA-based Complexity Studies by Tomoaki Suzudo
Dr. Suzudo's fascinating and distinctive three-state von Neumann rules are a significant contribution to self-organization research in CAs. I imported several of the "springiest" examples into Cellsprings, but since then he has discovered still others that appear to rival the first installment. Suzudo's site features a small applet to demo his rules, so check 'em out. And maybe some enterprising soul would like to try entering and saving them in Cellsprings for us.
Schaller's CAOS applet
Martin Schaller, a doctoral student at CERN, has posted the best applet I've seen for running one-dimensional CAs. 1-D CAs offer much of the behavioral richness of 2-D CAs in a simpler model, making it possible to view whole CA histories at a glance. But seeing is believing, so load CAOS and set the display to Size=1/Flow=scroll and the rule group to Sites=5/Rule=symmetric, making sure that Init=random. Wow! An extraordinary world of interacting gliders. Now explore other 5-site symmetric rules by toggling rule-bits along the right side (only some of which are enabled, because of the symmetry). You should find some more terrific rules in no time. Great stuff.
Stephen Wolfram's CA Papers
Landmark articles by one of the leading lights in CA research. These are technical treatments, but more accessible than most such. I'm living proof that a non-mathematician can get something from them. Also, Wolfram's well-implemented HTML is an example others would do well to emulate for the format of online research articles.
The Primordial Soup Kitchen
The website of mathematician David Griffeath, an expert on self-organization in CAs and discoverer of the CA "type specimen" in that regard, the Cyclic CA. A huge amount of CA lore reposes here (far more than I myself have found time to examine), much of it decidedly "high-end" in nature. Besides providing details, often Java-activated, of Griffeath's own cutting-edge research, the site keeps abreast of sundry CA-oriented developments across the Web.
Paul's Page of Conway's Life Miscellany
This site features a very convenient catalogue of Java-animated Life patterns that Paul Callahan created from Hensel's collection. Callahan's applet is actually more than just an animator, though - it's an innovative little Life simulator in its own right. And there's much else to interest the CA-tician in his "miscellany".
Scott Robert Ladd's LifeBox applet
This visually appealing CA applet by an expert Java programmer and author is home to the Swirl rule. LifeBox also runs other Moore OT rules with or without low-depth refractory decay. In addition, Ladd's site features a number of other intriguing applets in the complexity studies vein.
