When I was in college, it was a thing for students to design and build a digital LED clock out of random logic. A friend of mine wanted to make one that would tell time only in 15 minute chunks, as nobody needed more precise time than that.
Yes, I did a digital clock, too, my first digital design/build. It never did work right.
