Design and the Elastic Mind, MoMA
This was a phenomenal exhibition. I'm going to it a third time, and even bought the catalog, which is beautifully designed by Irma Boom (if you like typography, check out the cover and title page).
Lots of ITP alumni and adjunct faculty, and a lot of current information visualization designers like Brad Paley, Sep Kamvar, Jonathan Harris and Jason Wishnow.
Lisa Strausfeld and James N. Sears, NY Times cover
Dimitri Tyler, Hypothetical Drawings
Dan Phiffer and Mushon Zer-Aviv's pcomp project: Atlas Gloves
Christian Schmidt (ITP adjunct faculty) and Lisa Strausfeld's OLPC's operating system, "Sugar"
Probably more ITPers' works that are not mentioned here.
