Generates synthetic datasets for training and evaluating vision models on pattern symmetry and mirroring tasks. Each sample contains a random scatter pattern on one half of a grid that must be mirrored symmetrically to the other half.
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.

The scene shows a grid with a random scatter pattern on the left half. Expand the scatter pattern symmetrically to the right half by mirroring it across the vertical axis, creating a complete symmetric pattern.

| Initial Frame Random scatter on left half of grid |
Animation Pattern mirrored across vertical axis |
Final Frame Complete symmetric scatter pattern |
Create a vertically symmetric pattern by mirroring a random scatter from one half of the grid to the other half.
- Grid structure: Regular grid with vertical center axis
- Initial pattern: Random scattered elements on left half
- Symmetry axis: Vertical center line (left-right mirror)
- Pattern type: Disconnected random scatter (not continuous shape)
- Mirroring direction: Left to right across vertical axis
- Background: White grid with clear axis indication
- Goal: Create perfect mirror symmetry across vertical center
- Random scatter pattern (discontinuous elements)
- Vertical axis symmetry (left-right mirroring)
- Pixel-perfect symmetric placement
- Grid-based positioning for precise alignment
- Tests understanding of reflection symmetry
- Multiple scattered elements to mirror
