Hi

I have a facility which uses css and ajax to perform live plotting of 
routes between two London underground stations. The css plots are 
overlayed over a London Underground map, with each station as a hotspot. 
The underlying platform is Ruby on Rails.

I have incorporated certain Web 2.0 features like votes for the best 
routes, station name autocomplete, context sensitive points of interest 
along the selected routes etc.

The URL is http://public.ok2life.com/tube/routes. As usual, let me know 
if you have any feedback by either using the provided MessageBoard, or 
send me an email.

David
