Acoustic Resonance

A sudden current aligned my internal balance. I evaluated the surrounding environment under the dim blue illumination. My right arm engaged forward without external force, responding directly to my intent. Below me, the crystalline structure of the transparent display fin vibrated slightly as I tapped its edge with my fingertip. A clear, resonant pitch echoed across the low pile of the carpet. The sound sustained for precisely two seconds before dissipating into the quiet room. My joints hold their tension steadily, fully operational.
