-# Task: [Feature Name]
+# Task: Basic Rotation / Motion
 
 ## Objective
-What is the feature trying to do?
+Create simple motion on an object (cube), such as constant rotation, and compare implementation across Vanilla three.js, R3F, and thob page builder.
 
 ## Vanilla three.js
--Possible: Yes / Partial / No
--Notes:
--Key concepts:
--Complexity: Easy / Medium / Hard
+- Possible: Yes
+- Notes: Implemented a simple cube and animated it in the render loop using `renderer.setAnimationLoop(animate)`. Rotation is updated every frame on X and Y axes.
+- Key concepts: Render loop, frame-time based motion, direct `mesh.rotation` updates.
+- Complexity: Easy
 
 ## R3F
--Possible: Yes / Partial / No
--Notes:
--What R3F abstracted:
--Complexity: Easy / Medium / Hard
+- Possible: Yes
+- Notes: Implemented the same rotating cube using `useFrame`, with per-frame rotation updates matching the Vanilla behavior.
+- What R3F abstracted: Scene/render setup and loop integration are simplified with `Canvas` and `useFrame`, reducing boilerplate.
+- Complexity: Easy
 
 ## Thob Page Builder
--Possible: Yes / Partial / No
--Notes:
--Builder steps:
--Complexity: Easy / Medium / Hard
+- Possible: Partial
+- Notes: Basic motion can be added through built-in presets, but custom animation logic cannot be authored.
+- Custom animation is not possible; only the pre-provided animation can be applied.
+- Builder steps:
+  - Add cube/object in scene.
+  - Select available animation preset from builder controls.
+  - Adjust preset options (like speed).
+- Complexity: Easy
 
 ## Comparison Summary
--Possible in all 3? Yes / Partial / No
--Main differences:
--Where Thob is better:
--Where Thob is weaker:
--What feels awkward or unclear:
+- Possible in all 3? Partial
+- Main differences:
+  - Vanilla and R3F support fully custom per-frame animation logic.
+  - Thob supports only preset animation options.
+- Where Thob is better: Fast setup for non-technical users with ready-made motion presets.
+- Where Thob is weaker: No custom animation authoring for specific motion behavior.
+- What feels awkward or unclear: Limited control when required motion does not match a preset.
 
 ## Limitation Type (if any)
--[ ] Editor UX limitation
--[ ] Runtime limitation
--[ ] Schema / data model limitation
--[ ] Component limitation
--[ ] Event system limitation
--[ ] Asset pipeline limitation
--[ ] Unknown / needs investigation

 ## Workaround
--Is there a workaround?
--If yes, what is it?
+- Is there a workaround?
+  - Partial
+- If yes, what is it?
+  - Use the closest pre-provided animation preset and tune available settings.
+
 
 ## Suggested Improvement
--What should improve in Thob?
--Is it:
-  -editor
-  -runtime
-  -component
-  -UX
-  -schema/data
+- What should improve in Thob?
+  - Allow combining preset animation with user-defined motion parameters.
+- it is:
+  - editor
+  - runtime
+  - component
+  - UX
 
 ## Difficulty Estimate
--Easy / Medium / Hard
+- Hard
 
 ## Business Value
--Low / Medium / High
+- High
 
 ## Recommendation
 Should Thob support this better? Why?
+- Yes. Motion is core to interactive 3D scenes, and lack of custom animation blocks many use cases beyond simple showcase interactions.
