Art mobs are unofficial audio tours of MoMA. Before you head off to the museum you download the audio files and listen to commentary that you can’t get with the audio guides that MoMa offers, the audio also offers some music. I personally think this is going to be they way that a lot of people tour museums in the next few years (audio meta data, tagging…etc). Another interesting thing would be to add photos as well as recording your own and publishing those back. Rocketboom has the video of all this! Link.
