Your rainbow panorama enters into a dialogue with the existing architecture and reinforces what is assured beforehand, that is to say the view of the city. I have created a space which virtually erases the boundaries between inside and outside – where people become a little uncertain as to whether they have stepped into a work or into a part of the museum. This uncertainty is important to me, as it encourages people to think and sense beyond the limits within which they are accustomed to moving.
