Generates synthetic datasets for training and evaluating vision models on pattern recognition and sequential reasoning tasks. Each sample contains a large-small alternating size sequence where the next figure must be selected from multiple choices.

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 has two separated areas: a top SEQUENCE area and a bottom CHOICES area. In the SEQUENCE area, the shapes are the same shape and the same color, and their sizes strictly alternate between LARGE and SMALL from left to right. First observe the size-alternation pattern and determine whether the next item should be LARGE or SMALL, then select the one correct option (out of 4) in the CHOICES area that continues the same shape, color, and large/small alternation pattern. Circle the correct option and show the full process step by step.

Initial Frame Large-small alternating sequence and 4 choices	Animation Correct option identified and circled	Final Frame Answer circled in choices area

Identify the large-small alternating size pattern in a sequence and select the correct next figure from multiple choices.

• Sequence area: Shapes alternating between large and small (left to right)
• Choices area: 4 candidate options for next figure
• Pattern constraints: Same shape, same color, alternating size
• Alternation pattern: Large → Small → Large → Small (or Small → Large → Small → Large)
• Task: Identify alternation pattern, find matching option, circle it
• Background: White with clear area separation
• Goal: Select the one option that continues the alternation correctly

• Size alternation pattern recognition
• Binary large/small classification
• Multiple choice selection task
• Tests understanding of alternating sequences
• Shape and color consistency verification
• Visual IQ test style reasoning
