Moco Edu is a SloMoCo workshop focusing on tools and experiences that support both movement and computing learning objectives at entry-level. danceON is a domain-specific language and a web app that allows users to create interactive graphics overlaid on video from pre-recorded or live (webcam) sources. Over the coming year, we invite creators and developers to use danceON, develop educational worked examples, propose improvements, and develop their own extensions.
