Squeaky Croquet

It's well worth it for those people interested in working with Croquet to spend a good week or so learning about Squeak. Squeak is a modern, open source, highly portable, fast and full-featured implementation of the powerful Smalltalk programming language and environment (the original object oriented language). You may be familiar with other open source languages like Ruby or Python, but Squeak takes these concepts much, much further offering a true uniform fully reflective environment - real live objects. Croquet's relationship to Squeak gives Croquet the property of a purely object-oriented system. This allows for significant flexibility in the design and the nature of the protocols and architectures that have been developed for Croquet. There are many books and tutorials to find out about finding senders (alt-n) and implementers (alt-m) of methods, saving images (click-on-desktop-to-get-world-menu-then-'save-as'), etc. The best of the books is Squeak: Object-Oriented Design with Multimedia Applications by Mark Guzdial, Prentice-Hall, 2000.
