A team of artists, technologists and designers in Germany have created a device which they believe can block wireless surveillance.

The machine, called Cyborg Unplug, works by detecting wireless networks in the surrounding area and then acting against that signal.

BBC Click spoke to the team about their reasons for inventing the device and the issue of privacy in today's society.
