Very cool idea. On a technical note, you could define three macros \equity{10}{90} % where the units are percentages, and \balance{8}{10} \RandC{8}{10} % where the units are in mm and use this level of abstraction in your source code. I suggest, the diagrams in a separate column to support the narration, but with tikz you could even put them inline. These examples should get you started if you want to "program" your graphics: http://piratepad.net/GVsgD6x5D3 http://piratepad.net/GVsgD6x5D3 Speaking of power tools for graphics, check out also http://www.math.ubc.ca/~cass/piscript/ http://www.math.ubc.ca/~cass/piscript/ and the there-associated book http://www.math.ubc.ca/~cass/graphics/manual/ http://www.math.ubc.ca/~cass/graphics/manual/
