In the video : [REBOL VID demonstration](http://www.youtube.com/watch?v=IAy9tBHiLJo) - Nenad Rakocevic demonstrates what seems the basic code to compose a Rebol IDE at runtime.

Can someone provide a working Rebol example on how to create, update / modify faces (widget / control) within a View (window) at runtime.

So far the examples I found allow creating faces into a new window rather than update an existing one.

Thanks
