zhuzhiliao
Traditional toy that makes a wah-wah sound when it spins
Zhuzhiliao is a browser simulation of the traditional Chinese bamboo cicada toy that makes a distinctive sound when swung in circles. The experience runs from a single dependency-free HTML file and can work offline without a build step or backend. Touch gestures, automatic swinging, and mobile motion sensors can drive the virtual toy. A fixed-step physics model simulates gravity, an elastic string, drag, tension, and rotational speed.
