I have released a new tutorial for RapidWeaver Classroom subscribers covering Shadowbox with video. Shadowbox is a javascript box that is similar to the Greybox that has already been covered here, but it provides a bit of a different visual effect and it is increasing in popularity as a method of displaying video. In addition to the video tutorial I have provided the necessary Shadowbox files for download, along with a set of snippets to simplify the setup.
