(via beyond the beyond) Christopher Baker did a beautiful installation in Copenhagen, where viewers send SMS messages to a building and their questions and answers become part of the building and the sonic environment.

It does much more than simply projecting onto a large surface. The digital information interacts with the architectural features of the building, going around windows, with its own physics and gravity. Lately I've been thinking about the coming convergence of the digital and physical worlds (augmented reality, an internet of things, unmediated user interfaces). It's already starting to happen.
This installation is a great example of how it would feel to have digital data truly integrated with the environment, as opposed to being a self-contained projection or veneer. The next step would be enabling the data to change the physical structure...
I live for the day when Bladerunner is outdated, as long as we can unplug whenever we want to.
