The three circular mirrors are all different shapes to get different effects. The center one is a normal flat mirror. The left one is a concave mirror (using sphere shape). The right one is a pointy mirror (using cone shape). Because the main effect is mirrors reflecting off other mirrors and there's plenty of other reflections and refractions through the glass bunny, green sphere, and puddle of water, I had to increase the depth significantly to get the desired effect. This came at a cost of dramatically increasing the render time.
