Eight separate icons in a 4x2 grid, each on pure black square background. Each icon is rendered in the same style as the primary spark: white incandescent core with electric blue glow halo, heavy film grain, soft fuzzy edges, hand-airbrushed feel. The icons are: (1) four-point asymmetric sparkle, (2) lowercase letter d in chunky rounded bubble typography, (3) rounded square outline with sparkle inside, (4) three concentric sine wave lines, (5) scalloped circular seal with sparkle in center, (6) 3x3 grid of small sparkles, (7) vertical barcode of varying-width bars, (8) crosshair target with center dot and crosshatch lines. All icons same visual weight, same glow intensity, same grain texture. Y2K spiritual aesthetic.
