Light shows by Japanese artist Ryoji Ikeda in Amsterdam

From Friday evening (June 6), the light show work by Japanese artist Ryoji Ikeda will be visible on 4 locations in Amsterdam.

From the Dream Amsterdam website:
Ikeda will use pure light as the material for his interventions in four locations under the title of spectra :: amsterdam. His intensely bright light installations will appear mysteriously, connecting connecting a constellation of points across the cityscape.
