UK map for Power Grid
Chris Jones has designed a wonderful UK map for Power Grid (Funkenschlag) and published it to BoardGameGeek.com. He has posted more details here. A full (low-res) image of the map is available here and the high resolution images are available here:
Each file should be printed 26cm wide by 36cm tall (the exact dimensions of the Power Grid board). It would be best to get the file into a graphics editor, half it, and printing each piece onto A4 paper (for those not in the US).
