Null geodesics around a rotating reflecting surface with spin a = 0.94 and surface radius R = 1.01 r₊, where r₊ is the radius an event horizon with the corresponding spin would have had. The geodesics are directed towards a far-away observer in the negative x-direction having an inclination i = 60°. The image plane parameters (α, β) are (2, 2), (2, −2), ( − 2, 2) and ( − 2, −2) GM/c².
