In this chapter there are a number of handy plug-ins you can use for creating light boxes and slide shows (or combining the two), making rotating billboards for placing advertising or news updates, or making objects pulsate as you pass the mouse over them. There are also plug-ins to help you create professional looking charts with the help of Google Charts, to present YouTube videos in a variety of ways with a single function call, and to play sounds in response to events or for any other reason.
