This series is made up of one photograph of each neon light illuminating the stairwell of the construction site during work on the Tour Mozart in Issy-les-Moulineaux.

This procedure was used to produce two prior series in addition to this one. Both of the earlier versions were in 2009, when the building had fewer floors, and were made in a different stairwell. This third series, like the prior ones, constituted an exercise in seeing and an opportunity for surprise and for philosophy.
