The folks at Urban Mapping have just introduced the Panamap for NYC and Chicago. The Panamap takes advantage of a process called lenticular printing which produces three different images in one depending on what angle you look it. You may have seen this used in Cracker Jack prizes or Sportflix baseball cards (I might be dating myself with that last reference). This allows a lot of information to be shown on a single map without overcluttering it to the point of unreadability. The three viewpoints for each city show street view, neighborhood layout, and subway routes all on the same map. Just tilt it slightly to get the view you need. The short flash video below demonstrates it all nicely. The maps will retail for just under $20 and other cities may be planned.
