Hi Jean,

FWIW:

As the "Pure Magic" advocate that I am, I doubt that I would restrict
myself to UP in such dynamic map presentation case.

For example, your triangles would most likely need to be image
controls for which the positions are expressions. In this case, I am
not sure about transparency which is likely to be necessary to get a
proper visual effect. 'Gif' integration with Hot Fudge or something
else maybe.

With RC, I think you may embed a browser control directly on your RC
form. Maybe the start of an idea.
