I've been asked to produce a simple packshot for TMN for father's day campaign, where they wanted to show the Sony Xperia, a phone claimed that it would not scratch or even ruin if it would be put underwater.
It merely involved making it spinning, but i thought it would be nice to throw some dust particles at him, while it spins and shakes everything off, remaining pristine and clean.
Ultimately the client ended up using a real footage of the phone underwater...
