Plasma Energy Field

Static shot with internal motion: Electric plasma energy dances within a spherical field against complete darkness. Purple and blue electrical arcs branch and fork randomly, creating lightning-like patterns that constantly change. The energy pulses with varying intensity - sometimes bright flashes, sometimes dim glow. Where multiple arcs converge, bright nodes of light form temporarily before dispersing. The plasma creates its own illumination, casting subtle light on imaginary boundaries of the sphere. Some tendrils reach toward the edges, others coil back toward the center. The movement is chaotic yet contained, energetic yet balanced. Occasional bright flares create bloom and lens effects.
