How to make a sequence of 5 LEDs turn on and stay on until a switch is closed.

I want to create a circuit that utilizes 5 LEDs to indicate the passage of one minute. Once the LEDs are on, they should remain on until a switch is closed. In other words, after 12 seconds the first LED will turn on, and after each 12-second interval, the next LED will turn on until all five are on at 1 minute. The LEDs should remain on until a switch is closed. Once the switch is open again, the sequence will repeat.

Sounds OK. How do you propose to do this?
