Frederick Vandenbosch made a binary clock with Raspberry Pi Zero and Unicorn pHAT. He documented the whole process on his blog:
At the center of the project are a PiZero and a Unicorn pHAT. The PiZero fetches the time, converts it to binary and controls the Unicorn pHAT with a Python script. The Unicorn pHAT’s RGB LED matrix can be used to display those binary values in any colour.
