Photos: World's fair to focus on water

Spain plans to host Expo Zaragoza 2008, an international exposition in the Spanish city that will showcase technology concerning water and sustainability from more than 90 countries. The show is being regulated by the Bureau International des Expositions (BIE), the regulatory commission that formed after the Exposition Universelle of 1889 (in Paris) of Eiffel Tower fame.

The expo is already offering free desktop images (shown here) and screensavers to promote the event.
