The Mine Kafon ball is a large wind-powered device, heavy enough to detonate landmines as it rolls across the ground. Massoud Hassani drew inspiration for the project from his childhood growing up on the outskirts of Kabul, where he would play around the minefields with homemade, wind-powered toys.

Created for public interaction and engagement with the surrounding space, this sculpture draws the viewer in with its refined surface and startling optical effects of depth and dimension. From a body of Kapoor's work of mirrorlike pieces that reflect or distort the viewer and the surroundings and suggest the notion of continuous space, it offers a dazzling experience of light and a startling optical effect. Deeply rooted metaphysical polarities are at play in Kapoor's work: presence and absence, being and nonbeing, solidity and intangibility, and he draws on both Western and Eastern cultures for inspiration. His intention to engage the viewer and provoke a physical and visceral response is achieved in this reflective sculpture with its faceted facade that fuses the work, the viewer, and the environment into one pixelated, constantly fluctuating mosaic.

The distance and angle that one stands from the mirror's surface affects how the image of the viewer is reflected. This is a very interesting work of art in that it brings the curiosity out in the viewer and creates a dance-like interaction with the sculpture, as one's tendency is to move around in front of the piece to see how that changes one's perception of it. The viewer can actually "create" their own visual experience based on how they stand and move in front of the mirrors.
