Numbers of products that man has designed and developed based on similar philosophy- ‘objects within objects’, depict the same concept of utilizing the space within and protecting from outside environment.
Aircraft needs to be sheltered inside the hangar (plate 2A) from outside protection and for servicing purposes. The creativity of famous Russian Dolls (plate 2B) is based on the same concept. The smallest doll is protected by the next larger doll and goes on to put one onside the other. Hand tools (plate 2C) are kept inside a box for protection from losing them. It all so helps to organize according to shape, size and the nature of work.
