Concept for: an advanced spreadsheet "Information Cube"

The spreadsheet programs of today are still based on the principles of the first one ( Visicalc from Apple). But this concept could be much more powerful, if it would be thought through from the basics and if all possibilities of newer software would be integrated:

A modern spreadsheet program should have following features, which could be classified for usage to beginners, advanced and professional; so that nobody gets overwhelmed with the available features. That means also, that excellent new kinds of tutorials will have to be developed:

• use of several dimensions, using ordered tuples of numbers, not combinations of letters and numbers. ( as is has been developed in mathematics for matrix calculus for instance.
• use mathematical formulas, as written in mathematics
• present the spreadsheet of several dimensions, in some standard forms, but also allow the customer, to define the presentation himself. Cuts through the information cube; different sequences of cells. ( look at  http://www.thebrain.com/    to see,  how an elegant and intuitive navgigation in large amounts of information can be realized nowadays )
• indexing all cells, so that each piece of information can be found easily. The information cube can contain all kinds of information, like numbers, words, texts, pictures etc.
• expand the number of cells, so that a spreadsheet can have as many cells, as the computer of the user can store or the network of computers, to which he has access.
• use better, much more detailed colour schemes, so that cells can be better differentiated.
• supply add ons like:

•      Statistics and distribution functions; Monte Carlo Simulation
•     simulation of industries, social systems and economies, according to the      method of industrial dynamics, as  developed by  Forrester
•  differential equations or any other kind of equations
•  memorising methods, according to the flashcard principles
