Made after observing the sounds of (unseen) birds around Granville Island and on campus at ECUAD. A small motor and two yellow LEDs go off periodically. The original intention was to activate the movement using ambient sounds, but a simple timer circuit gave the desired effect. Installed under a skylight in a quiet stairwell at ECUAD.
