STPsim is an application that simulates and visualizes switches using the Spanning Tree Protocol. It features a GUI to build and control a custom network topology. A VPython frontend visualizes virtual switches and network cables in a 3D environment. To visualize STP-states, switches and ports change colors and captions in real time.
