Limitee invited SRJ to design the 14th T-shirt of their series, focusing on meditation in schools. With this T-shirt we wanted to give some attention to the centerpiece of our body: the heart. Ruiter took his own heart as an example. Working behind the computer his heart rate measured 72 beats a minute, which results into 4.315 beats an hour. These heartbeats are symbolized by 4.315 black dots. How many heartbeats do we have a week? A month? A year? These numbers show on the back of the T-shirt. The heart is a bizarre machine!
