Adjacency Matrix
A square matrix of cells is read by a head running the main diagonal, each row lighting its entries together with their mirrored partners below the diagonal.

Discrete
15 animationsBreadth-First Frontier
A lattice of dots carries a breadth-first frontier outward from a source, each ring lighting as the wave reaches it and dimming to a settled visited state behind it.
CSSEulerian Circuit
A closed one-stroke walk over the complete graph on five vertices, a traced arc running the circuit and using every edge exactly once before it closes.
CSSGray Code Disc
Four concentric code tracks carry the bits of a reflected binary word and click round one sector at a time under a fixed reader, exactly one track changing at each step.
CSSHuffman Merge
A row of frequency bars sends its two lightest subtrees up to join at a parent node, the prefix code tree assembling upward in merge order.
CSSInteger Partition
A Young diagram of unit cells reshapes as a single block leaves the end of the longest row and lands at the end of the shortest, the total staying fixed.
CSSLattice Path
A grid of streets carries a monotone staircase path from corner to corner that re-routes between three alternatives, each staying below the diagonal.
CSSLinear Recurrence
A row of tally columns whose heights satisfy a two-term recurrence: a span bracket steps right across the last two and the next column rises to their sum.
CSSMaximum Flow
A bundle of capacity pipes runs from a source rail to a sink rail carrying dashed flow, the saturated pipes held brighter while a minimum-cut rule returns to the narrowest crossing.
CSSPascal's Triangle
A triangular array of cells in which each adjacent pair slides together into the cell beneath it, the summing wave descending the triangle row by row.
CSSPermutation Wiring
Six lanes are crossed by a chain of transpositions and the strands re-draw left to right behind a wipe front, resolving into the permutation the network composes.
CSSProper Colouring
A tiling of distorted quadrilaterals settles into a proper two-tone colouring, the regions taking their tone column by column so no two neighbours ever match.
CSSRecursive Transfer
Three pegs carry a graded stack of bars and the two upper discs replay the recursive transfer, one lifting clear and crossing to a new peg at a time.
CSSRound-Robin Colouring
Eight points joined by every chord, with one round of the edge colouring lit at a time as the perfect matching rotates through the seven-round draw.
CSSSpanning Tree
A scatter of nodes sits under a faint web of candidate edges while the minimum spanning tree draws itself one cheapest edge at a time until every node is reached.
