Since you mentioned Project Based Learning, have you see Alan Kay's DVD on how he supports such learning on Squeak? http://www.squeakersfilm.org/ http://www.squeakland.org/sqmedia/movies/html/clips.html (Clips from the file on this page.)

Since you mention your site runs on Ruby-On-Rails, have you seen what Squeak Smalltalk and Seaside can do? Seaside is a native Smalltalk web dev environment using continuations to preserve application-object state rather than preserving page/session state. Jon Udell also interviewed Avi Bryant who developed Seaside and DabbleDB on Squeak. http://weblog.infoworld.com/udell/2006/11/15.html http://onsmalltalk.com/programming/smalltalk/seaside/making-a-connection-pool-for-glorp-in-seaside/ (Smalltalk's answer to Ruby-On-Rails, when linked with Glorp and Magritte) http://www.seaside.st/Videos/ http://onsmalltalk.com/programming/smalltalk/screencast-how-to-build-a-blog-in-15-minutes-with-seaside/

Hi Graham, Since you mentioned you enjoyed teaching Smalltalk, I'm curious if you know about what Alan Kay (the inventor of Smalltalk), Seymour Papert (Constructivism educator), and David Smith (3D game inventor), are creating (technology wise) that supports many of the topics you're interested in that you mentioned to Jon in the interview? He's creating "Croquet" a free, open-source, peer-2-peer, massive multi-player, 3D, constructivism based, environment all on top of Squeak Smalltalk. http://en.wikipedia.org/wiki/Croquet_Project http://www.croquetconsortium.org http://mslive.sonicfoundry.com/mslive/Viewer/NoPopupRedirector.aspx?peid=172f6de5-135b-4ba0-9207-ac6d383812c9&shouldResize=False# (Video demo)
