An old-rooted endeavour of man, i.e. fabrication of material and structures taking inspiration from nature, is again actively pursued under a renewed name: biomimesis. This approach, once belonging to the realm of biological sciences, is based on the observation that, when one tries to embody our recognition criteria for biological organisms in an explicit list, nothing can be found on that list that cannot be mimicked by some inorganic system. Hence, a large variety of artifacts can be made, all possessing, to some extent, life-like features. Biomimetic arguments are today common reasoning in experimental studies about `origin-of-life' and in `advanced robotics'; a relatively new entry pertains to the area of `material science'.
