It's rare that we get excited over maps, but this idea by graphic designers Jack Schulze and Matt Webb would be great for GPSs, combining 3D, first person and overhead views into one übermap.
The art project, called Here & There, bends the world into horizon-less, roller coaster loop topography, which allows the viewer to see their position from the first person perspective (complete with those 3D buildings that usually just get in the way) alongside the route/terrain to come.
For now, the designers' work is available in limited edition prints only that go for $65 (per a set of two). But we can still dream that someone like Google, Apple or Garmin might come around and drop a big pile of money on the small agency before automating this visualization for real time navigation.
