On Friday March 23, 30-40 students at Nottingham University congregated in the Portland Building and threw their own unauthorised and unorthodox party.

A silent disco is a variation on the flash mob concept. Groups of people are encouraged to make their way to a designated place at a set time and dance to music played on individual mp3 players.

The event had been organised using the Facebook social networking site and the 'group' set up to organise it has attracted some 479 members.

University authorities seemed largely uninterested in the strange group of dancers, while passers-by more bemused than they were put out, despite the sizable throng of participants.
