space invaders clock uses aliens to tell time

Electronics enthusiast Jason Hickner has built this fun clock that uses a game of Space Invaders to display the current time.

To make his Space Invaders clock, he took a funky old Sony portable TV, combined with a circuit that generates the video to create the game.

Can’t figure out how the time is displayed? Each extra life represents hours, while each alien on screen is a minute. You can also just check for the last four digits of the high score if that’s too complicated for you.
