Bennett Haselton – “ Mirror Spin ”
Country: ???
Authors description: I have been a collector and promoter of gadgets and curiosities for many years. This sphere with a spiral slot is one of my favorite spinners. I painted the slot white to make the effect more attractive. I discovered this illusion of movement when I put the sphere to spin on an inner mirror vertex. The sphere seems to go backwards when spinning clockwise and forwards when spinning counterclockwise. The effect is more noticeable when the sphere is brought closer to the mirrors and when orange caps are placed as reference. As with other illusions such as chromostereopsis, some people don’t perceive the illusion of movement.

Tatsuaki Kamoi – “ InfiniFlow Mirror ”
Country: ???
Authors description: InfiniFlow Mirror” is an infinity mirror that allows light to flow in the depth direction. The “Infinity Mirror” is a device that creates the illusion of an infinite number of light sources through a mirror effect. However, because it is a mirror, even if multiple light sources are turned on in sequence, the direction is reversed in the mirror image area and light does not flow in the depth direction. “InfiniFlow Mirror” has unlocked this restriction and enables new expressions.! It can separate normal and inverted images by shaped grooves on the wall surface.
