Thanks to Eleanor Hooper of Pif-Paf Theatre for these photos of a fascinating exhibit – the Celestial Sound Cloud.

See http://www.pif-paf.co.uk/portfolio/celestial-sound-cloud/ for more details of Pif-Paf and this intriguing project 

which demonstrates the ethereal effects which can be achieved through exploiting the sideglow properties of optical fibre.

The display is designed to span an area of 6 x 3 metres and works to best effect if it can be installed 3 metres above the ground.
