As a DANT award winner, I have spent the last 3 months working on a digital recreation of the Nan Giese Art Gallery in a digital space. The goal was to create an experience similar but also separate to the original gallery, for people to openly explore, as well as a way to preserve the gallery long after it is shut down.
The download of the program is free and there are versions for both macOS and Windows, and they, along with all necessary instructions can be found in the link below or through exploring the DANT website.
