This is a demo video of Instant DJ, one of three applications of Sprint Center Interactive Wall. All you have to do is just call the number on display and play by pressing the keys. It will even send you a text with a link to the song you composed after you hang up. Although I was using my iPhone on the demo, it works with any phones of any carriers! (It doesn’t have to be Sprint phones or any smart phones.) To learn more about the project, please see vimeo.com/4025588
