The CBC is reporting that MIT architects are planning to produce a building that has walls of water. The Digital Water Pavilion, will be created for Expo 2008 in Zaragoza, Spain, and will have walls of water created by thousands of computer-controlled jets. Using technology similar to an ink-jet printer, only on a much larger scale, the walls will be able to display images and be turned off or on in order to allow people to pass through them. The pavilion will house a cafe and at a cost of about $6000 per square meter, if my math is correct, I hope they sell a bunch of lattes! It's interesting in a technological sense but I don't think it would withstand our Canadian winters. Personally, I think this is a much better use of ink-jet technology and I'll bet it didn't cost $3,000,000.
