WASHINGTON — A new exhibit at the National Portrait Gallery fuses art and technology in an unusual homage to American history. Wearing Google Glass, Google’s latest toy billed as the first “wearable computer,” visitors simply look at a certain area of the 12-feet wide exhibit, the technology senses where it is aimed and a small retina display screen shows relevant information and media—anything from a JFK speech to a commercial about chicken nuggets.

The exhibit drew large crowds Monday, the last day it was on display, as visitors waited in line for more than an hour to use the Gallery’s Google Glass to interact with the artwork.
