Derek Eland

The British artist Derek Eland made an installation called the Diary Room. It was at a public space in the UK and the residents of the area to write down what the want to change and loved about the city they lived in, using coloured post-it notes. Over the time of 6 weeks there were more than 4000 post-it notes in the end. The resulting work was titled 'This could be Carlisle or anywhere' and was re-created as a 54 foot long installation in Carlisle's Tullie House Museum and Art Gallery.
