I discovered this beautiful project via Good magazine: In Bb 2.0 is "a collaborative spoken-word and music mosaic that sees a grid of 20 YouTube players on a single page. You can play them all at once or one at a time, or in any combination, in any order." You don't just passively listen; you actually play the page. The artists collaborated to produce In Bb 2.0, and you collaborate with them. Try it.
