The design idea is inspired by the website Fracturespace, which used 3d shape to represent the sound being changed by the timbre. In my design, users can press the button to add all kinds of shapes to the sketch. After the shape is on the sketch, users can change the frequency of the sound while changing the position of the mouse, and the shape and size of the shape they chose will also change. When the mouse is pressed, the color of the shape will also change according to the amplitude determined by the length of the time mouse is pressed.
The idea of the sketch is basically a game in which the little ball is controlled by the mouse. When the mouse moves, the frequency of the sound will be changed while the position of the ball is changing. The ball will also drop when the mouse is pressed and released, and when it dropped, a stage will appear and its height is based in where the ball dropped.
