For the last couple months a friend and I have been working on a 4000 series based clock in electronics class. After having failed building a FM receiver, we opted for a clock. We didn't go the microcontroller way, but old school ICs. So, we created a circuit for a simple clock. I opted for a 24-hour version, while my friend made the 12-hour equivalent.
