The Art Institute of Chicago — like any great, acclaimed, monstrous museum — is not the kind of place you can just pop by, drop in and dabble. To really see what interests you and to make the most out of your time (and, now that it costs 18 bucks, money), you need a plan. You need a map. An interactive map would be even better.

So here it is. The museum just launched a new interactive floor plan and gallery tour on its Web site. Nicely dubbed Pathfinder, the map allows you to click your way through the hallways, galleries and libraries, showing you the hallmark pieces and information about each spot. You can thus plan your attack and move through the place like a ninja.

"The Modern Wing has really been the impetus for numerous widespread changes in the ways the museum makes itself accessible to all visitors, both virtual and real," James Cuno, president and Eloise W. Martin Director of the Art Institute, says in a statement. "We have a new building, with its fresh approach to our collections, to the city, and to the landscape around us. And now, with our new interactive pathfinder on the web, we are bringing these fresh approaches to the hundreds of thousands of people who come to our website seeking information about our museum and collections."
