Pong
This is a basic demo of how to create a game of pong with JavaScript and HTML 2D Canvas Context.
A live demo is available online at http://pong.cwelsh.com if you're interested in taking a look.
Controls
The controls are shared between both players on the same device, so it works best if you use a touch-capable device such as an iPhone or iPad. Mouse support is also in place.
