Artists from the Gaffa Gallery installed a series of falling giant Tetris pieces in an alleyway in Sydney. They write:

There are grand implications of error here that lead to questions, such as who exactly has been playing Giant Tetris? What were they trying to do? Could I have done better? Is the city grid similar to a computer game or different? What brain-space am I in when I’m playing games on my computer? Is it more or less alert than when I’m waiting in line for a sandwich? The work seeks to challenge conceptions of the North end of Sydney’s CBD as an orderly, socially cold grid and beckons viewers to assess their own level of interaction, play and hacking within the city
