I just love maps. I always have. I used to spend hours with the Delorme Street Atlas CD-ROM until the company dropped Mac support. Of course the CD map business is mostly dead with online maps and easy access from computers, smartphones, and tablets.
Recently, I've spent some hours with a free universal iOS app called Recce-London. It is a rendered 3D map of central London, and will be great for visitors to the Olympic Games. The app lets you explore London; you can find restaurants, transportation, landmarks and more.
The graphics are reminiscent of SimCity. You can rotate the 3D vie
