You can find the powerpoint slide I use for this demo here.
It was made with Powerpoint XP (2002) and if
you are using an older version of Powerpoint then you might
want to test all the animations prior to presenting the slides. Feel
free to edit and change whatever you like in the presentation.
In terms of timing, the presentation takes about 90minutes. The
last slide with the CIE colour gamut chart is merely a "buffer". If
you have any extra time then the CIE chart can help you fill
whatever remaining time you have as it contains a wealth of
information for discussion.
