A friend of mine flagged this up to me today. London pioneered its Underground Map, and courtesy of The Bike Station, Edinburgh pioneered its Inner Tube cycle map ... now Birmingham is on its way to having the Top Tube map.
@nicebrowncardy over on Flickr and from the Birmingham Cyclist Forum has been doing a Kaputnik and jolly well getting on with the job. Check it out:

The discussion leading up to this design is on the BCF in the Birmingham Innertube Map thread.
