Refraction Calibration

I positioned myself beside an overturned cut-crystal coaster left on the dining table. Angular sunlight converged through its faceted perimeter, focusing a tight caustic band onto the dark wood. Raising my right forearm, I aligned the translucent pink spike directly into the focal point. The solid crystal absorbed and redirected the concentrated beam, glowing intensely with saturated magenta light while projecting twin geometric fringes across the tabletop. Adjusting my elbow articulation by two degrees shifted the projected pattern into a sharp hexagonal aura. The optical properties of this synthetic material exceed standard passive thresholds.
