3d matrix representation of cubical shapes for

[adquery]

I have only visio 2000 available and looked at different marketing and
diagram shapes to give a cubic representation of colour-coded status
information in three dimensions.

The ultimate goal is to create a powerpoint presentation to senior management.
Therefore this is not intended as a mathematical exercise, but should be a
neat rendition of an information cube in 3d.

Are there any other options or shapes available to achieve this goal?

thanks
