Check out this Seeing Double Wall Clock. It might look like your standard wall clock at first glance, but peer closer and you’ll find out that it features both minute and hour readings on the same set of markers in different colors. The only way to tell the time in a concise manner would be to have the clock hands (in greed and red transparent film) move over the respective marker, where everything will then become clear. The $108 price tag is definitely cringe inducing though – who’d pay so much for something as simple as this?
