We look from one item to the other in connecting interpretations. Each meaning of the adjacent item increases the understanding of the others. At the end, you come in contact with a very essential characteristic of the person or the group of items . Every time we do this exercise with somebody, this person feels really understood. In the analytic, detailed 'negative' way of looking the meaning of the items has a destabilizing effect as there is going on a constant evaluation and comparison with the meaning of the adjacent item.
Conclusions are closed and negatively biased, trying to 'separate' something.
Creativity runs higher and the general 'energy' household of a person is heightened. This Meta View is more than simple holistic viewing. I suggest very badly to do this small exercise above with some friends together. They work all with wheels. The 3 wheeler gets excluded as it's a toy and all the other contain some electronics.
