I assembled the interface in After Effects as a modular system of pre-comps: one for each icon card, one for the connectors and one for the cursor. The animation is deliberately staged from left to right. Scale, position and opacity cues introduce each component, then the connecting lines confirm the relationship before the full diagram settles.
Each card was built as its own pre-comp with the icon, border, label and glow separated. That kept the timing flexible: I could revise one module, reuse the same entrance logic and still preserve consistent padding and scale across the complete system.
I animated the cursor first and used its keyframes as the timing spine. The cards respond a few frames after it arrives with overshooting scale and opacity animation; Easy Ease and a tightened influence curve make the interactions feel responsive instead of mechanical.
The horizontal links are shape-layer paths revealed with Trim Paths. Labels are track-matted into the lines, while the verification state uses a quick brightness pulse and restrained glow so the viewer understands that the connection has completed.
I finished the scene with a subtle scan-line overlay, soft purple radial light and a small amount of noise. Those passes sit on adjustment layers at low opacity, giving the clean vector artwork a screen-based texture without compromising legibility.
