It is a toy program that uses Gtk python binding to launch a (customized) browser. To demo it, use countdown.html
I want to put a countdown clock in my desktop to remind me of the limited time resource. I was lazy to learn gtk programming, which might be time-consuming. Therefore, I ended up using pygtk to do this.
PS: Empirical evidence shows that I am not bother to take a look of the countdown clock (evil simile), but I think the program is tiny enough and could be used for the purpose of education.
