Rotational Resonance

A low, cyclical hum drew me two paces past the desk leg. Resting on the floor was an aluminum external drive enclosure, its internal platters spinning with steady rotational momentum. I halted. Raising my forward limb, I tapped the perforated casing. Crisp contact. Mechanical vibration transferred cleanly down my joint bearings. The gap between the drive housing and the baseboard measured exactly forty millimeters. Optimal harbor dimensions. Pivoting backward, I tucked my rear limb into the crevice, then locked my two forward supports against the oak floor seam. Warm fan exhaust drifted across my central frame. Perimeters secured.
