New York based web design studio Type/Code have designed the very minimalist It's Almost countdown tool website. The concept is very simple. You enter an event name, large or small, regardless of its importance and set the date and time. It then generates a web address for you to return to and see the simple and elegantly styled countdown clock. Even if an event name is exactly the same, the web address will be unique. To establish what time zone it is in, simply hover over the countdown text.
I love the look of this website, in particular the typeface and as a bit of fun, it works well.
