To give you a couple of cooltown classic scenarios, consider traveling to a museum with tags on all the pictures. Using a device that you are comfortable using, you could view more in depth information about the pictures without typing URLs. The pages designed for the painting could include information about other paintings or artifacts in the museum and maps to their location. In this way the virtual medium of the Web leads you to a new path in the physical world.
Of course there are many existing information systems for museums and some leverage the web. Our system differs by being a horizontal technology rather than a museum technology. We want you to enjoy web presence while you are in the museum and when you leave.
