Neon lights and deep shadows, pitch-black darkness and moonlight, familiar spaces and unknown premonitions. In the glaring light, the colours shine out, symbols of life and joy; in the twilight, one senses a sense of unease. ‘Through my perception of the atmosphere, I sense the nature of the environment I find myself in. This perception therefore has two sides: on the one hand, the environment, which radiates a certain mood; on the other hand, myself, in that I participate in this mood through my state of mind and realise within it that I am here now.
