poème > visual effects. The visual effects of the Poème were conceived by Le Corbusier and Louis Kalff, and realized through a number of projection devices. They consisted of: two hanging objects receiving a fluorescent light (“volumes”), chromatic zones inside the pavilion (“ambiances”), coloured spots projected around the écrans (“tritrous”), other projected elements and glittering bulbs (“special effects”). The effects were reported on a "minutage" or score, that managed their scheduling second by second.
