In this work in progress we present early results in the process of understanding how interactive dance visualizations can inspire coordinated dance moves between dancers in informal contexts. Inspired by observations at nightclubs and parties with DJs, we designed an interactive dance visualization prototype called "Canvas Dance" and evaluated it in a user study with 3 small groups of people. We conclude by offering a set of design considerations for future work on interactive dance visualizations for non-professional dancers in informal contexts.
