Yet another thing that keeps getting re-implemented :)

I think I first saw it as "vis" in the 1980s.  Yeah, the man page
says:

       Originally written by Dan Heller (argv at sri-spam.arpa).

       It has been substantially enhanced and generalized by  George  M.  Sipe
       (currently  -  7/88,  at  rebel!george) to the point where Dan would no
       longer recognize it.

There's a more recent 'vis' that has no similarities (other than being
a program of some sort, etc), so I have tended to rename the older one
'vvis'

I also recall another version of the same thing that you could type
commands at while it was running, but I can't find that one now.
