Animated video explanations, interactive charts, maps, diagrams, flowcharts — any topic clearly and step by step
Mathematics — animated graph construction of functions, limits, series. Step-by-step theorem proofs — each step appears with animation. Visualization of Fourier series, Laplace transforms, integrals. 3D surfaces, rotation, cross-sections. Physics — body motion, collisions, pendulums, waves. Electric fields, field lines. Optics — refraction, diffraction, interference. Algorithms & programming — step-by-step visualization: sorting, graph traversal, trees, A*, Dijkstra. Data structures — how stacks, queues, hash tables work. Recursion — visually, with call stack unfolding. Geometry — animated geometric proofs, Pythagorean theorem, inscribed circles, fractals. Transformations: rotation, reflection, scaling. Any process — chemical reactions, biological processes, economic models. Anything that can be explained visually — can be animated.
A student is preparing for an algorithms exam.
Result: two MP4 files. First — step-by-step quicksort animation with pivot highlighting, array partitioning, recursive calls. Second — parallel comparison: two arrays sorted simultaneously by different algorithms, showing the difference in operation count.
