Sony Ericsson 'Sharapova Demoslam' by Dare

Each Demoslam on the site uses a Google mobile app in an unusual way to demonstrate to show off its capabilities.

With her Xperia X10 in one hand and her racket in the other, Ms Sharapova uses Google's Search by Voice to find answers to multiple choice questions.

She answers each one by blasting tennis balls at the 3 human targets cowering on the other side of the net - namely the agency producer, a Dare creative and the client.
