At Elastic{ON} 2017, an innovative keynote performance featured a ballerina outfitted with sensors to capture biometric and motion data, which was visualized in real-time using the Elastic Stack. The project, known as the Ballerina Project, aimed to demonstrate the creative and unexpected applications of Elastic's technology by visualizing heart rate, acceleration, location, and sound data during a ballet performance. Despite challenges like embedding technology into the ballerina's costume and ensuring the visualizations were understandable to the audience, the project highlighted how the Elastic Stack can transform data into compelling stories. The successful execution of this performance underscored Elastic's commitment to pushing technological boundaries and inspiring curiosity and innovation among its audience.
