Hi Ben,
There is the ROLayoutTranslator hierarchy that is used to have smooth animation. Indeed, a signalUpdate is done at every relevant steps.
By the way, have you tried:

| view |
view := ROMondrianViewBuilder new.
ROMondrianExample new chooseLayoutOn: view.
view open

This could be useful to researchers as well as teaching demonstrations to students. The benefit for Roassal of being 'the platform' for researchers to develop and test their layout algorithms, would be ending up with all the latest and greatest of these built-in.
