Ruby on Rails

I think one of the things you might need is a 'timer', which will let
your code 'sleep' before calling again your 'how_finished' function. I
have never done this but remember reading about it, I googled for
'javascript sleep timer' and one of the links I found was this:

In order to communicate with the server from Javascript I would look
into Prototype or jQuery. They simplify enormously the code in
Javascript to be able to communicate with your server using AJAX.

I hope this gets you started.
