Created at Fabrica by Alex Rothera, Ivor Williams, Jacopo Atzori, and Aaron Gillett, Flutter is an experimental app concept designed specifically for grieving adolescents. It uses music to help those experiencing the loss of a loved one – a period of time often resulting in high levels of isolation and incredibly difficult emotional problems – express themselves in a safe, positive environment, by creating sound artefacts that express how they feel at that moment.
