Here's an interesting development from the Fryderyk Chopin Institute (http://chopin.nifc.pl):
"The Institute will soon release the GPS guide for smart phones devoted to Polish and Norwegian composers. Follow in the footsteps of the great composers. Five guides containing biographical entries of 350 people and descriptions of 370 places associated with Chopin, Tellefsen, Grieg, Lutosławski and Nordheimon a single application. An excellent compendium of knowledge about the people and places that shaped and influenced the creative personalities of these great composers. This application will help you discover the links between Polish and Norwegian musical culture."
More details in January apparently.
Thanks, Mark. It'll be interesting to hear if anyone decides to take up this offer.
