Many Meccano humanoids are constantly running along their individual rail line. They go up and down, straight and around, passing others with whom they sometimes interact. At times, they willingly join another humanoid’s rail and run together in harmony, or they fall by accident on someone else’s rail and struggle to escape from the right owner. The rail sometimes breaks and some of the runners fall without remission, while others, despite reaching breaking point, are able to hold on and go back to a safe straight line and continue their journey. A beautiful conceptual approach to what human life is.
