I'm somewhat more inspired by Scanwiches, cross sections of (obviously) sandwiches. http://scanwiches.com/
And in a similar vein, microscopic images of alcoholic beverages: http://www.insanetwist.com/2011/08/microscopic-images-of-alcoholic-drinks.html
Not photographs, by the way - he's actually scanning the candy.
I believe twice "identify the Candy bar from the cross-section" has been a video round at the quiz night I frequent. We have done quite well in these rounds.
