This was my initial idea, showing a random trivia for the time digits shown on the clock. The top bar represents seconds progress and the ':' blinks on each second. This clockface has light & dark themes.
Graph Calculator Clock
This was my final submission for the challenge. Current hour is represented in a graph paper, with seconds filling each cell. Progress of the hours for current day is shown by buttons of a calculator. The weather is displayed in the solar panel and the HH:MM:ss time is shown on LED panel of the calculator.
