The utopian Calmoduline Monument is based on the property of a protein, calmodulin, to bond selectively to calcium. Exterior physical constraints (wind,rain, etc.) modify the electric potential of the cellular membranes of a plant and consequently the flux of calcium. However, the calcium controls the expression of the calmoduline gene. The plant can thus, when there is a stimulus, modify its « typical » growth pattern. So the basic principle of this monumental sculpture is that to the extent that they could be picked up and transported, these signals could be enlarged, translated into colors and shapes, and show the plant’s « decisions ». This permanent show, installed in a public place, would suggest a level of fundamental biological activity.
