I've tried to enter in the Louvre demo, it takes 10 minutes to load the Java applet and my IExprorer crashed closing all the opened browsers windows. Are there any demonstration not written in Java ? thanks. Ale.

Has anyone looked at hyperbolic trees? I find them hard to explain, but very easy to grasp once you play with them. Try:
http://www.inxight.com/Content/7.html
The Library of Congress demo is especially nice.
I think a hyperbolic tree would make a great UI for a class browser, maybe as a replacement for the left-most pane. It would definately help a new user like myself get a feel for which classes belong where in the hierarchy.
Unfortunately I don't know if we could put one in Squeak without permission from Inxight. I know they hold license to their implementation of hyperbolic trees, but I don't know if they somehow own the idea also. I've never understood that sort of thing very well.
They are a Xerox company, by the way. It's another neat idea from PARC.

How does the Squeak Smalltalk to C translation handle Smalltalk code that contains Blcok context? It was my impression that it is difficult to program Block context in C.
Actually, it cannot translate real blocks. The translator only translates a subset of Smalltalk, just enough to compile the interpreter. It does the usual optimization for ifTrue: and whileTrue: blocks, but can't handle full block closures.

I don't know of any non-java demos.
I'm running IE4 with the newest updates under NT Workstation 4.0 SP4, if that helps. The demos load and run fine.
If there is interest maybe I can do a screen grab and post it somewhere? You really won't be able to get the full effect unless you can play with it live, though.

The original hyperbolic circular groupings were done by the artist Esher -- at least "the look" is pretty well covered there. And it is not possible to patent an idea, only specific expressions and mechanisms of ideas. My guess is that such a Squeak browser would not violate anything. However, I'm not sure that doing a tree in a circle really adds much to traversing or understanding a hierarchy ...
Cheers,

The first time a saw a VRML demo I remember getting hit with the idea that a class browser you could walk inside of and see the relationships and even edit would be a fun way to explore. I agree that it may not be much more useful but it sure sounds like fun.
