1.5 Wall Cup

Recently I started a project looking at alternatives to the double walled SS cups that are used to insulate cups of coffee. One interesting alternative, made by Bodum for their Bistro line, are glass double walled cups. My interest currently is in laser-cutting the outer wall with patterns or useful shapes. 

Here is my first trial render. Currently i have not physically realistically modelled the cup and both the physical design and the graphics used are likely to change. This is just to show the idea.
