However, what’s more interesting to me is the whole project:

Inspired by a shared interest in the striking dress codes of various social groups, they have systematically documented numerous identities over the last 8 years.

I’ve often felt like this when looking at the pictures of the committee members of the square dance national conventions (52nd; look at any program from a past National for other examples). If you took the people and posed them identically, you could get a grid very much like those shown at the Exactitude site.
