Check out Tony Buzan & Nancy Margulies. Just page through Buzan's The Mind Map Book---no need to buy it---

MM's are messy, colorful, fun to do, fun to review, easy to add to w/ post-it notes

They are the glue for activation. They make it happen fast

Put'em on your door---walls--use large paper--get lots of colors---it's a gut kind of a thing. You just feel it all coming together, i.e., the big picture and where the pieces fit

good luck
