This web application is very simple. It uses the userís processing power (through javascript) to compute hexadecimal digits of Pi. Whenever the page is requested, the server finds the next piece of the problem to be solved, creates the javascript code to compute it, and then sends that code to the user requesting the web page. The javascript is then run on that personís computer, and the data is sent back to the server. Basically, I am borrowing a little bit of your processing power to help compute Pi. Thank you!
