Have you had a look at this Infographics extension on QlikBranch
One thing I did a few years ago when pitching Sense to the Board was knock up a viz that auto cycled through pictures of the Board members with some very complimentary text saying how each of them were amazing superheroes. They spent a lot more time watching the compliments to them auto play, than looking at the business data examples I'd spent ages working on.
They did open their wallets though and splash the cash.
Not Infographics per se, but this Play Button Qlik Sense Extension on Qlik Branch can add a bit of auto bling. It auto plays & selects dimension values that are then applied to all viz's the same as when one manually selects a dimension values.
I have forked it in GitHub to add the functionality for an option to continuously loop 'n cycle through dimension values.
Could be useful in a demo if you wish to talk the talk, whilst Qlik auto loops the loop.
