3D or 4D spreadsheet

[Frederic Parrenin <parrenin gmail com>]

Dear all,

This is a general / long term question.
Gnumeric, as other spreadsheet softwares, is 2D.
While I like very much the spreadsheet concept because it is so visual
and direct, I would like to apply it for solving complex 4D problems
(our physical space is 4D...).

Would it be possible to implement a 3D or 4D spreadsheet software?
Apart from the GUI problems, are they fundamental computation issues
with such a concept?

Best regards,

Frédéric
