I think this would be neat, although I wonder if a flow chart is the best way to go about it. It would be absolutely huge. Perhaps there would be a way to code it together so that you select an item name from a drop down menu and then it displays the ways that you can create that item (and the ways to create the items needed to create that item, if possible).

How are you going to plan it? Using a spreadsheet, or Visio, or on paper, or something else?
