Circlo is an ambient audiovisual clock. The ambient soundtrack by Hannu Kuosmanen changes depending on what time of day it is while the circles on the screen pulsate gently. The music is at its calmest around 1 am/pm, and gets more intense until the clock strikes 1 again.

Double-tap anywhere to access the settings screen where you can change the color scheme and turn the music on or off.

Design and programming by Johan Halin.
