This is interesting: Interactive Johari Window - Describe willa. I've never seen this before. The site says:

The Johari Window was invented by Joseph Luft and Harrington Ingram in the 1950s as a model for mapping personality awareness. By describing yourself from a fixed list of adjectives, then asking your friends and colleagues to describe you from the same list, a grid of overlap and difference can be built up.

I've picked six adjectives that I believe describe me; you can go and pick some, too, and then we can see if they overlap.
