The Sony Ericsson billboard campaign for their Xperia X10 smart phone is tiny. So small in fact that if you weren't careful you would've trodden on the little zooming ad convoy that whizzed around France to the delight of children and adults alike. Sure, the pedestrians probably couldn't see what the billboards even said but the cute factor is so high that it all plays out perfectly.

Micro-campaigns are popular in advertising with T-Mobile and Sony Playstation both jumping on the bandwagon and we're all up for this craze. Favourite part of the video is when the mini-bus follows the normal sized bus like a child playing dress-up in their mother's clothes.
