This all runs on your local machine (or indeed across the web if latency isn’t an issue). Once you have this running there is plenty of scope for creativity; use the heart rate data to drive a visualisation or crowdsource positional data using accelerometer and gyroscope to create a collaborative artwork. Instructions for setting up are at the readme here https://github.com/peted70/BandServerApp
