Technology in the actual artwork

We've been talking about technology for the arts (for arts managers), but here's a new twist. What about technology for art consumers? I just read a fascinating article about technology in the actual artwork itself. The Hello Cube at the Tate Modern was a modern interactive sculpture that you could tweet commands to and it would respond with changes in its patterns and colors. So people all over the world could interact with this installation, while people actually in the museum could see the changes reflected in real time. The Hello Cube also responded to voice commands. This exhibit was designed to bring younger people age 16 - 25 into the museum.

Here's a link to the article: http://www.technologyinthearts.org/2012/03/the-hello-cube-at-the-tate-modern-a-tweetable-installation/

The article goes on to talk about the possibility of twitter being used for other exhibits to make them more interactive. Could there be temporary twitter accounts set up for particular pieces of art that would allow viewers to get more information about the artist or piece? Would this really result in bringing younger people into the museum? Museums which are already short staffed and financially strapped might not be able to put manpower and finances toward such an endeavor, and may think of it as gimmicky. Technology has certainly changed the way people live their lives in general, so why wouldn't that change the way they spend their leisure and entertainment time and dollars as well. It might be short sighted for those in the arts to not consider events like these.
