The Javascript Calculator
You should first read the article by Simon Southwell[1].
Southwell's article is a step by step description of the features of this simulator, showing how to "cut" the photo of a calculator into several areas corresponding to the keys and to the digits, and how to simulate the behavior of a real calculator when the user presses the keys on the screen. On a computer without a touch-screen display the user must use the mouse to click the keys. On an iPad or tablet, the user simply presses the keys on the screen. Way cool!
