The technology we have available today might not have been put to the best use when it came to engaging users. That is the lasting impression I was left with after browsing through this site. The company (a transatlantic one) builds iPhone apps that take the music created by electronic artists, and then it lets you come up with tunes of your own by using the accelerometer from the iPhone along with the sounds that surround you. This is what the company calls “reactive music”. That is, music marked by activeness on the user instead of the passiveness of sitting while a song is playing, merely tapping your fingers away and so on.
