It’s a cool idea to make cell phone as a music toy. Some creators designed the similar games before, such as the ocarina, piano and guitar. These games seem interesting and creative. So, we started to develop a series of music toy game for children. In practice, we took more time to design the operation of game. This game needs to take cell phone as a music instrument. It should be able to operate easily if we hope this game can be fun. Furthermore, we also make graphics and interface design into a children's favorite look.
