Sculptural elements

Question. The wall arrangement will be 'random', staggered, and varied in size, style, etc. These elements, when concerned with photography, are two-dimensional. Will there be a third dimension?

• shadow boxes
• thick mounting
• prints displayed flat on the floor
• actual sculptural elements ie mandarine peel sitting on the floor
• shelves?
• the stack of books
• attachment/hanging techniques such as pins, thick double sided tape...
