I have already seem things like this Word chart and this GIF picture (and sincerely they inspired me) but what I have in mind is more than this. I wondered an application that generates the Techs section of RULES.TXT from blocks and arrows. If you know Simulink software (used in control engineering) it is easy get the idea. The blocks could be moved in the screen, to determine the age and category of every tech and dragging an arrow from one block to another gives the predecessor. I intend to create this application but before doing it I need to be certain that I am not doing something someone already done.
I am also looking for contributions (suggestions, pictures, programming). If you have any comments, I would be grateful.
