This is a clock. each marble equals 1 minute. you can tell the 10s minutes by the position of the box. the hour is shown by the number next to the bell, and whether it's AM or PM is shown by the cog. the date is shown by the circular screen, the day of the week is shown by...i don't know what to call it actually. the month is shown by the calendar, and the year/leap year is shown by the rectangular screen.
this project (especially the marble part) was inspired by https://scratch.mit.edu/projects/23645294/
