A wheelbarrow and tools covered in newspaper was one of several art installations on show at Lancaster University for an exhibition entitled "Watching Walls".

The artist Christine Dawson added 150 papier mache bricks labelled with the question "How will YOU save the planet?" for the art installation entitled "Sustainable Future?"

Another installation "Balanced Earth?" shows a pair of scales balancing bricks labelled Exclusion and Inclusion, while a pile of bricks labelled with words like "Hate" shows how people create their own barriers.

Christine said: "It's about asking people how you can change the wall within yourself to make the world more balanced, peaceful and harmonious. I want to use the bricks to symbolically dismantle the dark nature of walls."

This wall within is depicted by masses of knitted bricks covering real "unyielding" bricks while another installation "Brick Books" looks at barriers to learning.

Christine, who graduated from Lancaster University, is the current artist-in-residence at the Chaplaincy Centre on campus where the exhibition was held.

She said she wanted people to interact with all the installations.

"I have asked questions of the viewer to be answered on labels throughout the exhibition. I really like to democratise my work, involving as many people as possible."

Other artworks included a creative brick carving project and a yellow brick road completed with the help of REAP, a Lancaster University based organisation aimed at widening access to university, and Marsden Community College in Nelson.

Christine said her work is inspired by the writings of the art critic John Berger.

She said: "Berger defines the present historical period as "the time of the Wall" noting that although the Berlin Wall came down in 1989, many have since been erected - concrete, bureaucratic, surveillance, security, racist, zone walls. In conjunction with these he believes that walls of separation exist within us all."
