How frequently do we see what we have learnt to see, rather than what is actually there? In this installation, Light, and our perception of it, is both subject and medium. Is one half of the wall darker, or is the other lighter? A relativistic optical illusion conceals the underlying unity. In the context of Delhi, a city that I experienced as deeply segregated, the work reminds us of the importance of a shared conception of space. Installation created at KHOJ studios in Delhi, during an Arts Council International Fellowship.
