A visual timer for kids


I would like help figuring out how to make this special type of clock . I need some for my daughter, but don't want to shell out the $30 plus dollars for each one. It is basically counting down time in a visual way for children who are too young to understand numbers counting down.

I know there are computer based ones online, but it is not always convenient to have the computer on.

Thanks for any help!

Why not use an hourglass?

For times shorter than the full hour, mark the bulbs with different coloured lines ("you need to be tidy by the red line, because we're leaving at the blue line").
