The interactive exhibition opened on May 7, and since then more than 75,000 people have visited and placed sticky coloured dots on the walls and furniture in the room.
Dunedin Public Art Gallery spokesman Tim Pollack said it had been one of the gallery’s more successful exhibits.
"A very large number of those visitors were children and young families who were completely enamoured and delighted with the exhibition, and came back time and time again.
"It’s been a really successful exhibition. It has been so much fun for everyone involved. It’s been great."
The exhibition closed yesterday, and as part of the closing process, large numbers of people were invited to visit the room on Saturday, when there were spot prizes for people dressed up in the "dottiest costumes".
Mr Pollack said it was a fun way to wrap up the exhibition.
He said a "stop motion" video of the first two months of the exhibition revealed how the room had changed.
"It’s remarkable."
The final video of the exhibition would be available in about a week.
Due to its popularity, further interesting interactive exhibitions were in the pipeline.
