ARC-AGI
The Abstraction and Reasoning Corpus
...It consists of a curated set of tasks where models must infer patterns from input-output examples and apply those rules to new unseen cases, without relying on memorization or prior training data. The dataset is structured as grid-based puzzles, where each task requires understanding transformations such as symmetry, counting, or spatial manipulation. Unlike traditional machine learning benchmarks, ARC emphasizes generalization and reasoning over statistical pattern recognition, making it particularly challenging for current AI systems. The repository also includes a browser-based interface that allows humans to attempt solving the tasks manually, providing a baseline for comparison. -

OghamStars
Draw stars dynamically & adjust draw parameters in real time. Fun!
Starting with an N-gon of N sides we create an X gon with all possible interconnections, drawn not all at once but line-by-line. Transparency, color, and line thickness, draw speed, can all be adjusted. Symmetry can be maintained or broken. Algebra is given in the program that describes the number of points formed in the geometry, the number of overlapping triangles, the number of possible angles, and the number of lines, all equations based on the parameter 'X'. This program is good to get kids interested in math, and could be an easy addition to a course where students have been questioning the usefulness of algebra. ... -
