The device uses a servo motor to create a physical manifestation of a digital notification from a specific individual when they call you. Once a notification is passed to the particle cloud, the device initiates a wave of the flag, a gentle notification that runs 3 times to let you know the individual you have specified has sent you a notification. For example, if your partner calls you, this device allows you to see that they have tried to get in touch with you even if you have put your phone away for focus time. With further iteration we could implement different patterns of notification depending on the severity of the situation, but for now, just a gentle reminder is useful.
