I will read your writing.

I have interest in how from a workspace, one can compose spatially and 
timely several independents morphs without the need to formally define 
and instantiate model and view classes. Nothing super complex like a 
DrGeo view, but more handy, like how to compose a clock morph and few 
sliders to adjust the time.

In the other hand, may be, before doing that, do we need a more 
complete/uniform widget framework. Something like Polymorph or equivalent.

I am openly wondering.
