Why is there a huge pink face in Oxford's Broad Street?

The art installation, made from hundreds of post-it notes, has gone on display outside the History of Science Museum.

Passers-by are being asked to sign parts of the face and leave their ideas for how public sculptures around the city can be made more diverse.

It's part of a project by Oxford University that has also seen two female busts installed next to the famous emperor heads that sit on plinths outside the Sheldonian Theatre.

Following controversy surrounding the statue of Cecil Rhodes at Oriel College in High Street, the university is asking for ideas about how artwork can be made more representative.
