How much computer do you use? Marcin Ignac wanted to know and so used a logging software (Tapper) to track his computer use “Every Day of My Life” for 2.5 years. Each day is represented in this picture by a line, the color representing the app opened in the foreground (i.e. being used). Black means the computer was off.
