Hi Phil,
Have you tried BabyUML? A horrible hack and not yet portable to other Squeaks, but it is a start.

This is set up for Windows, but the .image and .changes files should work anywhere (assuming the Squeak VM hasn't been improved so that it has�� lost backward compatibility).

Wow, that nails it quite nicely.

And it feels a lot like that, especially with tools like GT-Playground.

Now, the most complicated bit is for me to get the user to discuss with the object computer through the UI in a satisfying way. Getting the right UI for delivering the value is taking a very long time.
