Ondes de verre
Architect Odile Decq, head of ODBC, has created a restaurant inside the Opéra Garnier in Paris - with the constraint of not touching pillars or ceilings, of remaining completely reversible, should the restaurant be closed at the end of its lease. (See here for the site of the restaurant "l'Opéra", and here for the Website of ODBC) Ondulationg glass walls weave around the pillars and provide very special reflecting surfaces.
The white mezzanine makes the reflections a bit awkward to catch; nevertheless, the results are unique and quite surprising: you seem to be seeing the Flatiron building transposed from New York to Paris. Also, the reflection drives a wedge though the vaulted ceiling, blending old and new, inside and outside - a degree of freedom reserved for the photographer whose substance of work is ephemeral.
