Free your mind with freemind
I have been using Freemind tool extensively for my current project at work. Freemind is basically an open source mind mapping tool. It enables an engineer (or any designer in general) to visually co-relate a number of complicated concepts. This has been of invaluable help to me since my current project spans lots of different and diverse components and I am suppose to track and make sure everything continues to work in sync without any problem.
