Love this installation. Over the course of a few weeks, thousands of children visiting a space in the Gallery of Modern Art in Australia were invited to leave a small, colourful, sticky mark. The result is wonderfully stunning. This following quote sums the project—and generally the principal of keeping things simple—nicely.
"As with many of Kusama’s installations, the work is disarmingly simple in its elemental composition; however, it brilliantly exploits the framework of its presentation. The white room is gradually obliterated over the course of the exhibition, the space changing measurably with the passage of time as the dots accumulate as a result of thousands and thousands of collaborators."
