Use when animation involves depth, perspective, volume, or three-dimensional awareness—camera moves, character positioning, environmental interaction, or maintaining consistent spatial relationships.

Think like a sculptor working in time. Your characters exist in three-dimensional space, even on a 2D screen. Every frame is a frozen moment in a world with depth.
Generates design tokens/docs from CSS/Tailwind/styled-components codebases, audits visual consistency across 10 dimensions, detects AI slop in UI.
Records polished WebM UI demo videos of web apps using Playwright with cursor overlay, natural pacing, and three-phase scripting. Activates for demo, walkthrough, screen recording, or tutorial requests.
Delivers idiomatic Kotlin patterns for null safety, immutability, sealed classes, coroutines, Flows, extensions, DSL builders, and Gradle DSL. Use when writing, reviewing, refactoring, or designing Kotlin code.

Before animating anything, ask: Where is this in 3D space, and how does it move through that space?
Animation is 4D: three spatial dimensions plus time. Characters have fronts and backs. Rooms have depth. Actions travel along vectors through real (imagined) environments.
Solid Drawing — The foundation of spatial thinking. Every object has volume. Turn it around in your mind. Know what the back looks like. Draw through forms, not around them.
Arcs — All movement happens in 3D space. An arm swinging traces a curve through depth, not just across the screen. Think spherical paths, not flat shapes.
Staging — Spatial composition. Where in the Z-axis is each element? Foreground, midground, background create depth. Overlap establishes position in space.
Squash & Stretch — Deformation happens in 3D. When a ball squashes, it spreads outward in all directions, not just sideways. Maintain volume in depth.
Anticipation — Movement into the screen reads differently than across it. Anticipation toward camera: foreshortening increases. Away: forms recede.
Follow Through & Overlapping Action — Trailing elements exist in 3D. Hair doesn't just swing left-right; it wraps around forms, falls with gravity, catches on shoulders.
Secondary Action — Supporting elements occupy their own spatial positions. A cape occupies the space behind a character. Spatial consistency sells reality.
Timing — Depth affects perceived timing. Objects moving toward/away from camera have different visual rhythms than horizontal movement. Foreshortening compresses distance.
Slow In & Slow Out — Acceleration reads differently in depth. Objects approaching camera grow rapidly at the end (looming effect). Factor Z-axis speed changes.
Exaggeration — Spatial exaggeration includes depth. Characters can lean impossibly far into frame. Environments can stretch beyond physical possibility while maintaining spatial logic.
Appeal — Dynamic spatial composition is appealing. Interesting angles, depth variation, and dimensional poses create visual interest.
Straight Ahead & Pose to Pose — 3D motion paths are easier to plan (pose to pose). Complex spatial action benefits from knowing key positions in space before animating between them.
Spatial Awareness Checklist:
Common Spatial Errors:
When animation feels "flat":
When space feels "confusing":
Thinking in Depth:
The screen is a window, not a canvas. You're not decorating a flat surface—you're revealing a world that extends in all directions. Every element occupies a position in that world. Honor the space.
