Once upon a time, maybe over 2.000 years ago and probably in the Siberian taiga, someone watched the hares moving easily through the snow. How could they go forth over such an irregular terrain with uncertain depth with thay efficiency? Well, the answer was right before them: the hares’ legs are natural snowshoes that allow them to jump around the snow without sinking into it. Sometimes, we only need to observe nature in order to solve the problems we must face.
