Thank you. Truth be told, I, too, spent a lot of time with those applets.

Of course.

Yes, probably. Depends on how this programs are written.

Wikipedia has a good article on 4d and reeferences

No, not at all. Modern physics, based on the string theory, implies that the world we are living in is actually 20D or so.

Thank you
