This is wall LED clock. Despite to have only twenty LEDs it is full day clock showing time with 15 seconds precision. Is it really possible? May by these LEDs packs the time in so cryptic code that no ordinary human can read it. I believe the opposite is true: any person, who can read regular mechanical clock, can read it (after some explanations and examples. of course).
It uses an ATmega328p microcontroller, Adafruit LEDs, discrete components and a slice from a tree.
See the project on Instructables and the video below on setting the time.
