Amsterdam Light Festival 2014 featured “On the wings of freedom”, a light artwork by Aether and Hemera in Amsterdam.
A group of radiant butterflies, that hovers with hundreds at a time in a flight upwards. 'On the Wings of Freedom' is about the impressive way technology changes us as a society and how little we think about it.
