During six workshops at a local school, we managed to create a rainbow effect in one of the school’s hallways, with only three colour filters, a smoke machine and daylight. Working with people is always a fascinating adventure for me. Rainbow Hallway was certainly no exception: having not quite settled down yet in the beginning, the pupils from the ‘Miniemeninstituut’ enthusiastically brought about a wonderful spirit of cooperation. More important than the final result itself was bringing the school and the children to life during these three weeks, as if they themselves were the work of art.
