There will be a solid wall behind the cash table and a glass wall in front of the table. The glass wall is still not finished yet, later on the DC postcards images will mounted on the wall so that people can see it outside the kiosk. The purpose of the top is to let sun light projet the DC Postcards logo on the ground, and the size of it is similar to the table. The logo itself will also move when the sun light direction changes. The concept of this kiosk is work like a little national mall so we only have on table inside which means we have more space inside to people walk around and enjoy the DC postcards.
