Instead of death by PowerPoint with informative slides and pictures
but I do you could put up a video of an aquarium is a soothing
background to what you're talking about. And if you really wanted to
be creative you could add a few fish in the video with reminders about
moving the discussion along and the subject to be talking about in
that section of your talk.
That way you keep it interesting and relaxing and you could actually
have information up there that would be useful as you go through
something.
