I just got iThoughts, a mindmapping app that really helped (and is continuing to help) me organize my thoughts, brainstorms, inspirations and notes in a really cool way, here's an example of what one looks like:
http://dl.dropbox.com/u/36332877/Example.html , each of those bubbles can hold a note (which you can see by hovering over them, try it!), links to resources (if you click on it, it takes you to the thread I mentioned), or links to other maps. What I like about this app is that everything can be spread before me, if I just thought of something that would be cool to add to my centaur's culture, I just make a "child topic" that leads from the Centaurs topic and call the child topic "Culture" and then put down my thoughts in it so that it looks like: Vadra--->Peoples---->Centaurs---Culture. I tap culture and then I can see the notes on the culture of my centaurs.
A much more thorough explanation of the app can be seen here, it might help my fantasy oriented explanation make more sense:
http://www.ithoughts.co.uk/iThoughts/Ge ... arted.html I know that not everyone thinks as chaotically as I do, but I hope this helps some of you as much as it's helping me! It's for iphone, ipod touch, or ipad. The iphone/ipod version is $7.99, but it's worth it! If you like this kind of note-taking, but don't have an idevice, you might want to look up some computer mindmapping programs. I hope this is helpful to someone!
