At the peak of skeumorphic look&feel era the DMGMORI management wished / desired design elements that would reflect the world of metal processing industry within the graphical user interface (GUI). With a vast majority of the client‘s board members being iOS users during a time when iOS 6 was reigning the decision was obvious and understandable. A funny coincidence is that iOS 7 with a new flat design language was introduced just shortly after CELOS skeumorphic design has been approved. In our skeumorphic look&feel lab we were testing different materials and how to mix them with each other.
