Dig, Clock!: A customizable digital clock (2016)

Dig, Clock! is a digital clock that runs in a Linux terminal. The user can choose a 24-hour or 12-hour display, decide whether to play the Westminster Chimes on every quarter-hour or to run silently, and select from a variety of text and background colors.

Its numerals and AM/PM display are constructed using utf-8 characters, and present an attractive, seamless appearance.

Dig, Clock! was written in Python 2.7. The sound files were built using PySynth from Martin C. Doege, and play via the PyAudio bindings to PortAudio that were designed by Hubert Pham.

A suite of unit tests is included.
