I had not heard of this before, some of you may find it interesting.

If you ever run into the situation in which you need to have a computer sit out in the open to display a website for presentation, and the machine is pretty much going to be open to the public, there is a little known function built into Internet Explorer called Kiosk mode. It can be run easily enough by clicking "run", and typeing "iexplore -k".
The "-k" enables the kiosk mode, and opens up Internet Explorer to go to the full size of the screen. They can only click on things that would be located within the browser unless a person uses shortcut keys to move to other Windows functions. The only page that displays is whatever is set for the Home page. In other words, it is not possible to type in a new web address.
