IT is a task that would give the most experienced designers sleepless nights.

But digital design students from City of Glasgow College will have their work displayed to 100million people at the Royal Edinburgh Military Tattoo.

A link between college staff and the annual event has given 20 talented students the chance to show off their best efforts.

Dianne Barry, a lecturer in Computer Arts and Design at the college, with her colleague Andy Welsby, has set up links with the event's producer, Brigadier David Allfrey.

Together, they devised a brief for 20 students to design digital images for projection on to the walls of Edinburgh Castle. Chosen illustrations will be integrated into designs projected on to the castle's 80m by 85m 'canvas' and used as backdrops during the summer event, which opens today.

Dianne said: "It's really satisfying to deliver work like this and even more gratifying to see the students seizing the opportunity.

"They were so creative and so dedicated and constantly collaborated with each other, sharing ideas and techniques.

"The students met producer David Allfrey and did a recce of Edinburgh Castle before being divided into small teams and developing ideas. David came to Glasgow to see the work in development and was really impressed with them."

The partnership between the Tattoo and the college made a debut last year.

As this year's Tattoo will follow a theme of Homecoming and the Commonwealth, the students were tasked with creating images to reflect the range of performance groups from participating countries.

Janine Getty, 24, from Scotstoun, who is studying for an HND in Computer Arts and Design, said: "It's been an amazing opportunity to have people see my work and for me to start the process of getting my name out into the world as a professional artist.

"Taking part has already helped me get a job as I approached a digital creative collective in Glasgow to let them know about my experience with the Tattoo and have been working alongside them to set up an art exhibition in Glasgow."

An audience of 200,000 spectate at the Tattoo, while an estimated 100m tune in online and on television each year.

Brigadier Allfrey said: "I have hugely enjoyed working with City of Glasgow College staff and students.

"I am thrilled with the results."
