19th April to 19th May.

A screen, on the gallery wall, displays a grid divided into small rectangles. Each one of these can be electronically 'occupied' by someone. There is space for eight thousand one hundred and seventy people.

Visitors to the gallery are asked to take a postcard, located next to the screen, and follow the 'rules' - the instructions which explain how to take part. Participants then remotely select a rectangle on the screen, fill this with a pulsating colour, leave their name, location and a website they would like other people to visit. They are then asked to invite 5 of their friends to do the same.

As more people take part, so more rectangles became 'occupied'. The image changed on a daily basis and the work will be complete as soon as all of the rectangles are 'occupied'.

There were three ways to take part: Visit the Surface Gallery to collect the instructions, hearing about the instructions by word of mouth, or by being invited by someone who has already taken part.

Social connections will 'spread' around the Internet - each person 'digitally' touching the next.
