London - Territorial or Transport Links

I'd love to see (and help design) a London Map.
Territorially, it could be within the M25, or the North and South Circulars. Alternatively, it could just be the counties of Greater London, but i can't really see a way of dividing them up into 'continents' very easily.
Transport Links - The Underground map strikes me as the most obvious one to work on, with lines and/or geographical regions being continents. For a bigger map, perhaps the larger map that TfL publish that extends to areas outside London itself, (eg. Slough).
Alternate maps could consist of a simplified Tube map, with arterial rail, road and boat services.
A wider UK rail network based on regions and train line operators would also be great to see!
I would be more than happy to help design such maps, but as a total beginner, I would need some assistance along the way...
