Sprint Center is a large, multi-use indoor arena in downtown Kansas City, Missouri. They hold pretty big concerts such as Coldplay, Britney Spears etc.
This installation has 3 applications; Phone Painter, Now Widget, and Instant DJ. All you have to do is just call the number on display and play by speaking or pressing the keys. It will even send you a text with a link to the song you composed, art you drew 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.)
