The Cricket is a solar-powered musical instrument jewelry. It chirps in the sun and can be played by shading. The patterns on its front are not only for decoration but also touchable. The three areas control three oscillators respectively. Pressing them will increase the pitch, change the timbre, and speed up the rhythm. There is also a touch point on the back that will interfere with the output and produce noise. A clip can be attached to the back to wear it on clothes or bags. You can also put it in the grass, and you'll feel closer to summer.
