I would never have guessed this needed so much tinkering and electronics. It's not immediately clear because all the pics show the same light, but the color is controlled using an app and it has (apparently) 3-5h battery life. > Not only can our skirts match colors, they can chance in sync or strobe in complex patters across a group.
