This is the setup of the "Ice cold Artificial Moon" shot. I had a lot of trouble keeping the ice plate standing up. Finally I had put some plasticine behind and in front of it, put the whole thing on some tin foil and kept it additionally supported by the box where I had frozen the marble-in-ice in. The plasticine behind actually created a "shadow" I liked and which came in handy to create a darker part at the edge.
