On the widgets page, there's a flash countdown clock at the top of the page, but not as a widget. Has HE considered making the countdown clock available as a widget?
I guess you could look at the html for the page and use it, but it would be tricky if it loads any URLs and they are relative.
At this point, it probably wouldn't be worth putting together. The next two /8s allocated trigger the IANA pool depletion. APNIC and LACNIC are liable to put in their last request in the next 30 days; it's just a question of who does it first.
