Simple Javaccript / jQuery Page

We need one page that interactively and in real time will show information about our service. To be selected please send me three samples: - That you can use clock/counter: a JS that shows something every X seconds - That you can use jQuery to consume services: a JS that gets the latest USD/JPY rate (or any other currency rate) from Google API - That you can do animations: A JS that shows/removes 5 pixels white dots in a grey rectagle at random positions in random intervals. Send me those excersices and I will tell you what needs to be done privately. Then you can bid on the project. The first person that finish the excersices and gives a proper bid will gain the project. We do have more projects, so please bid wisely. Happy Bidding!
