Although not a hit with reviewers, Google's new Nexus Q media streamer has at least one secret feature which has people - and the device itself - talking.

The ball-shaped device is used primarily to stream movies and audio to a TV or speakers.

But if you tap several times on the Q's image in the app used to control it, a screen pops up asking if you have a "dilemma".

You can then ask the device a question about life, the universe and everything, and receive a response similar to those in 'Magic 8 Ball' toys.

Google is no stranger to pranks and easter eggs, of course - here are a few of our favourites.
