This tiny calculator is an easy way to perform linear interpolation. Once you arrive on the page you can do all of your data entry using the keyboard by using the Tab key to move between entry boxes.
The page is simple and uncluttered and offers a graphical proof of the result. The source is an example of HTML forms feeding variables into Javascript as well as basic use of the flot library (http://www.flotcharts.org/) which is built on top of jQuery.
