Another annotated scene from Hamlet. But wait, there's more.

The more is that note only is the text annotated but so is the video. Mousing over a character as the video plays invokes a pop-up comment. Those comments are spatial, so even if the characters moves, the comment remains available.

But the comments are also temporal; that is, as the scene plays, a comment changes to reflect the particular time a user invokes it. The comment for Hamlet at Time B is different from the comment for Hamlet at Time A.

The content here supposes this is a director giving advice to the actors.
