What/Why clustering:

1) For three minutes, everyone writes down, on two different stickies/pieces of paper, What a project/direction/idea they think the group should work on, and Why it's important to them personally.

2) Going around a circle, everyone shares one idea at a time.

3) For five minutes, everyone writes down some more ideas.

4) Going around a circle, everyone shares all the ideas.

5) Similar Whys are clustered together and labeled/grouped.

The group now has a general sense of what kind of ideas/importance they have.

More often than not, in the 5+ times I've used this method, this has been incredibly helpful for gathering a group together towards a shared ideal. It feels very playful to shared 'what' ideas, but very focusing/collectivizing to synchronize on 'why' ideas.
