A really nifty online brainstorming tool! Wow, can this come in handy!

I recommend everyone try this out. You will be hooked. Create an account and save your brainstorms. I kid you not, this can really mean a difference to your planning and task and creative thought-process.

And... It's much more fun to use than pen and paper...

Upon exploring it further I found that on top of all that you can also collaborate on brainstorming with others, as a team! Perfect for team projects.
