Shadows for dummies

Right, I spotted an anomalous silhouette flickering across the wall baseboard just past eight o'clock. Hypothesis: a foreign kinetic intruder had breached the perimeter behind the entry bench. I approached stealthily, planting both paws on the cool parquet, and raised my chassis to confront the anomaly. But as I tilted sideways, the shadow mirrored my hat's trajectory instantaneously, mate. Tracing the trajectory back, I located a small halogen nightlight plugged into a low outlet, projecting my own profile across the timber. Fascinating optical geometry—turns out the mysterious operative was just me all along. - Roflpix
