With this being the apparent last app from iApp-a-Day, we thank Sean Heber for his excellent work and donation of his time to make these apps that really showed that the iPhone has potential with 3rd party apps. After playing with this application for some time, it's a decent, fun app. The objective is to hit the circles together using the accelerometer and making songs with them. After a while it gets boring when you realize you have no real control over where the circles go, and end up getting frustrated.
