This image represents an invisible boundary that is the fourth wall, felt but never touched.
A metaphor used frequently in the theatre, art galleries & elsewhere
It serves to separate the observer from the observed.
‘Diderot’ is a visual portrayal of that intangible concept - blurred figures drifting across a reflective plane, present yet unreachable. Their distorted forms hint at a world we can see but not step into, a reminder that the fourth wall is less a barrier of space and more a boundary of perception.
