Reactor · Pulselive wallpaper

A row of teal and lilac bars sits along the bottom of a dark screen and bounces to the beat of whatever music is playing. The rest of the space stays empty, so icons and windows never fight for attention. You choose the low bar, high bar and background colors, plus the speed. A low key music visualizer for people who work with sound on.
