The installation did not include any interaction or player input at first as it was just generating some random patterns according the rules that I wrote. But Kevin’s saying that "everything seems arbitrary" enlightened me all in a sudden and I realized that I should allow the program to generate patterns according the players’ preferences. Therefore, some questions were added at the beginning to gather information needed; and lastly I inserted an audio of the “tic-tac” of a clock as the background “music” to echo and emphasize the "time" passing by.
