A group of UK students have won one of the top $50,000 (£33,000) cash prize in Microsoft's global technology innovation competition.
Eighty-seven student teams from 71 countries competed in the worldwide finals after winning local and online competitions. Microsoft has awarded cash and other prizes valued at more than $1 million throughout the year-long Imagine Cup competition.
Alex Bochenski, Jonathan Neuman, Edward Noel and Rob Parker got together at regional heats at Exeter University and formed the soundSYNK project as part of Team Colinked.
Colinked developed a mobile phone app that allows music across multiple devices to be synched and played together.
The app, which won the team the Innovation category prize, allows an "impromptu social network" to be created through bluetooth and WiFi, creating a form of "mesh networking".
The team said of their app: "When users connect their phones together, they have the ability to play the same song on all devices in perfect harmony, all working through known delays and pre-determined time intervals."
Alex Bochenski said: "Imagine being able to connect a stadium full of people by playing music and sounds through all their smartphones at the same time!"
