In Sep. 2009, Today Art Museum held an exhibition of the artist SUI Jianguo called “The Tension of Moving”. In the exhibition, there were two giant iron balls with the height of around 2.5m moving in the museum. However, during the preparing session, many creative thoughts could not be executed due to many limitations. In Nov. 2010, after more than a year’s preparation, the original thoughts of the artist could finally come true through the Today Digital Art Museum. This exhibition was like a multi-media work. When the audiences face the 3D digitalized space, the traditional pattern of viewing was broken and replaced with the medium of keyboard and mouse. Besides, the audiences were able to interact with the artworks like a video game.
