Exploring the Fascinating World of Cycloidal Curves

The central display board features the title "EXPLORING THE FASCINATING WORLD OF CYCLOIDAL CURVES". The board is divided into two sections: "THE GEOMETRY OF MOTION" which shows illustrative graphs for the Shortened, Common, and Extended cycloids, and "APPLICATIONS" which includes line art diagrams of the Tautochrone Property (a cycloidal pendulum clock) and a Gear Design. The overall setup is mounted on an aluminum frame with wooden side boxes containing electronics (likely an ESP32 or similar microcontroller, based on the previous context). In the foreground, a student wearing safety goggles holds a physical gear, suggesting hands-on use of a mathematics kit for learning kinematics.
