Reactor · Auroralive wallpaper

Teal aurora curtains rise behind a dark mountain ridge and mirror themselves in a still lake, under a violet sky dusted with stars. The ribbons of light react to the music playing on your computer, swelling and rippling with every beat. Perfect for late night playlists and anyone who wants a calm but living backdrop. In the settings you can change the speed and all three aurora colors, from the lower curtain up to the crown.
