Generates synthetic tasks where multiple shapes are displayed with exactly one being asymmetrical. The task is to identify and circle the asymmetrical shape with a red circle.
Each sample pairs a task (first frame + prompt describing what needs to happen) with its ground truth solution (final frame showing the result + video demonstrating how to achieve it). This structure enables both model evaluation and training.

Among the displayed shapes, exactly one is asymmetrical. Identify and circle that asymmetrical shape with a red circle. Do not change anything else.

| Initial Frame Multiple shapes without marking |
Animation Red circle drawn around asymmetrical shape |
Final Frame Asymmetrical shape identified and circled |
Identify the single asymmetrical shape among a group of shapes (where all others are symmetrical) and mark it with a red circle.
- Shape Count: 3-6 shapes per image
- Shape Types: Polygons (5-8 sides), stars (5-7 points), crosses
- Symmetry Status: All shapes except one are perfectly symmetrical
- Asymmetrical Shape: Created by intentionally perturbing vertex positions
- Circle Properties: Red circle (RGB: 255, 0, 0) completely enclosing the asymmetrical shape
- Spacing: Minimum 50px gap between shape bounding boxes to prevent overlap
- Non-overlapping placement: Shapes maintain minimum gap to ensure clear visibility
- Single correct answer: Exactly one asymmetrical shape per image
- Varied asymmetry: Different types of asymmetry (rotational, reflective)
- Random colors and sizes: Each shape has unique visual properties
- Smooth animation: Circle fades in progressively over the asymmetrical shape
- High-quality rendering: 1024×1024 resolution for clear shape details
