Mind the gap! The nfsLondonMetroMap3 screen saver puts the London Underground on your desktop. It's a great way to familiarize yourself with the Tube before traveling to London, or to reminisce after a trip to the city. The map includes information on station closures and other important details that are valid through 2011.

The screen saver is a quick download and runs smoothly. It's animated, with green blips representing trains moving through the stations. And it's quiet, so it would be appropriate for use in an office. My only quibble is the transparent NewFreenScreensavers.com logo that floats over a small bit of the map--but the screen saver is free, so it's hard to complain too loudly.

If you're traveling to London or want to commemorate a trip, load up nfsLondonMetroMap3 and enjoy.

Note: This updated version of the screen saver contains the current metro map as of August 2011.
