Brainstorming Exercises

I don't know if this should be posted here (maybe outwitting WB?), but I thought I would post it up for anyone who wanted it. When researching a project management issue some months ago, I came across this website. Some are more group activity (which, in theory, I guess could be used here) but I find them to be useful if I am stuck, or just want to come up with some new material or depth. I personally love the Why? Why? Why? . That one usually works for me.

ETA: These are more for project problem solving, but there is no reason they could not be adapted to fit writing specifically.
