During the contemporary art event, NUIT BLANCHE 2009, in Paris:
It is raining in St. Merri church…
It is raining concrete…
It is raining concrete feathers…                                               These feathers, which come from the sky, are made of virtual Craters Concrete .

A fragile and contradictory balance between harmony and chaos appears with this rain of feathers… The feathers belong to angels, who are losing them.

To discover all the feathers and angels, which are moving between paintings, furniture and other atypical objects so characteristic of St Merri church, you have to explore all of the space:
- “large feathers" are falling from the sky; some sway back and
forth towards the floor, while others are going down more hastily
- ”clouds of small feathers" are vibrating under the wings of
numerous sculptures and paintings of angels
- “virtual angels” are speaking and flapping their wings.

Every ten minutes you can hear the sound of the rain,
it is the deluge: all the feathers are now falling in a
downpour.
Is it due to the angels who are raging?
