We're all getting old. Sorry but it's true. Even if you're a toddler and somehow you're reading this, you're also getting old.
Since actual calendars and diaries have become a bit old hat in the face of all these damn computers and iPads, it's easier to forget how quick time passes. The cruel/clever designer Hiroyuki Miyake has developed a way of making us more aware of this.
He created the Measure Calendar, which converts each day of the year into a centimetre. Your life is therefore easily measured out in front of your eyes.
