A link from Stopmotion Pro cheers Mrs D considerably. It leads to a video of a public-participation live stop-motion event at the Kroller Muller Museum, Holland in 2013 where the public hand over found objects and the TAMTAM Objekten Theater team incorporate them into short animations using Stopmotion Pro software. You can watch a YouTube video of the actual event here.
It goes to show how simple it is to use anything to hand... together with a willing imagination and some animation skill... to create a stop-motion animation.
Problem for Mrs D is... her imagination ain't very willing at the moment.
