All material objects have a resting (or default) elevation, which can change due to user interaction. However, if an object changes its elevation, it should return to its resting elevation as soon ...

At the materials consultancy Material Connexion, the answer is simple: just reimagine the object’s primary purpose. The company helps connect assorted industries to material manufacturers, and ...
