Looking back at the history of World Expo's, I have a feeling that the future as something exiting, something approaching and something desirable.
Now in the year 2010, we are living the future, over 50% of the world's population live in urban areas, blah, blah, blah. City bikes, blah, blah and blah. We know.
To quote Håkan Hellström; "Give me somthing to build a dream upon".
