The idea comes from a scene I saw in the Best Buy in Boston. In the TV display area, a little boy saw the pinwheels spinning on the screen and he tried to grab the pinwheel on the screen but his father stopped him. This inspired me to do a project that people can interact with the pinwheels on the screen. Using a microphone as the sensor, users can blow the real pinwheels and the pinwheels in the video will spin. I’m going to put four different colored pinwheels. If users blows the pink and yellow one, the pink and yellow pinwheels on the screen will spin. If they stop blow, pinwheels will stop gratually. When all of the pinwheels spin, the background video will show something funny and surprising, such as butterflies fly.
