Researching for this article I came across the Treehugger post on Ustatic’s Wall Grass Concept. You must understand this concept before you can digest the Hour///Gras Living Wall Clock. Based on Ustatic’s theory that growing grass at home is beneficial, this concept clock encourages you to grow either grass or other suitable plants in a stainless steel and glass body frame and hang it on a wall. The hour and minute hand pass over the patch of grass and trim it via their sharpened edges and help maintain a pre-set level of grass-blade length.
