On the night before the longest day in 2004 a tension of teenagers from Luke4 youth group took to the pavements of the lower Newtownards road, Belfast. They had been granted permission from police city council and community leaders. They had chalk in hand, slogans in the head. Their aim: to make their mark in chalk on the streets. To name things normally observed but un-named: broken bottles, ripped up trees, derelict shops. Their aim: to write slogans that weren't trying to sell anything. To re-colour the road. To make themselves and others think, and perhaps think twice. The group worked from evening light into darkness.
