We now have a demo of this functionality, but unfortunately do not yet have permission from the vendor of the base software to distribute it to the public.
Note that this design was published in 1972, about two years before
the unfortunate design of today's computer-screen windows was promoted
out of Xerox PARC. (If I have any of these details wrong, I invite
