Flyer Symphony

This project aims to gather people in the park to enjoy the space and interact with other people. There are 7 colorful flyers, and each makes a distinct sound. The flyers contain information of a concert at the park, and has several tickets at the bottom with barcodes. When people take a barcode and bring it to the park concert, they realize that each ticket makes different bell sounds according to color. Together they form a symphony
