The neighbourhood tour above is an example of a video expanded with elements from across the web. At different points in the video we see elements from Wikipedia, Google Maps and Twitter, used to add context to the tour and the locations featured in it. Did you notice how all these elements are selectable and clickable? That's because they are separate from the video and loaded in dynamically based on the current position of the video timeline.

The example above is created with a tool called Popcorn Maker, created by Mozilla. Popcorn Maker makes it easy to enhance, remix and share web video. It lets you use your web browser to combine video and audio with content from the rest of the web — from text, links and maps to pictures and live feeds.

On the Popcorn Maker home page There are many other sample projects you can look at. These will give you some other ideas about how you could use Popcorn Maker to create interactive time-based experience online.
