Students hoping to follow in the footsteps of names including David Hockney and Tracey Emin have put their work on show in two exhibitions at a leading art college.

Almost 600 students from the Royal College of Art in London are taking part showing work including paintings, photographs and sculpture.

Among the exhibits is Japanese designer Tomomi Sayuda's work The Mask of Soul which she says was inspired by a karaoke session.

The mask comes complete with a fitted microphone and speaker which lets the wearer hide their identity while making their voice much louder.

Ms Sayuda said: "The mask of soul gives psychological strength to be able to speak in public.

"It's a black mask, which hides the speaker's identity and creates a small privacy in a public space.

"Its microphone picks up the speaker's voice and plays it loud from the speaker on the top of the mask.

"The idea is inspired by my personal experience of once having gone to karaoke with a very quiet shy friend, when he started to sing songs very loudly in the karaoke room."

The exhibition, called ShowRCA, takes place at the college's two campuses and has helped launch the careers of previous students who include Emin, Hockney and designer Orla Kiely.

Around 40,000 visitors are expected to attend.
