I love this!
Artist Yayoi Kusama created an inter-active installation entitled The Obliteration Room for the Gallery of Modern Art in Brisbane. Starting with a domestic environment every wall, chair, piano, table, and accessory was painted a brilliant white. Then over the course of two weeks, children who visited were given thousands of colored dot stickers and were invited to collaborate in the transformation of the space by placing stickers any and everywhere they wanted.
What a fun explosion of color!
