The decorating approach of Big World is centered around a straightforward theme that becomes intricate when put into practice. This theme highlights elements that shine and produce sound, creating an engaging visual and auditory environment. The use of reflective materials like mirrors, polished steel, and glass railings is extensive, enhancing the overall glimmer of the space.

In addition to the shiny surfaces, the atmosphere is filled with various noises such as beeping lights and loudspeakers, contributing to a vibrant and dynamic setting. The abundant reflective features create a multi-sensory experience, making it reminiscent of a disco ball, which emphasizes the complexity and layered nature of this seemingly simple decor theme.
