Five Levelss
One idea, explained five times — to a child, a teenager, an undergraduate, a doctoral student, and a peer — each level rebuilding what the last one simplified, with an interactive panel you can drive.
Knowledge graphs
One fact — "Santiago is the capital of Chile" — carried up five rungs. A child drags two bubbles and draws a labelled string between them; an expert manipulates the geometry of a scoring function and poisons a GraphRAG retrieval context. Same entities, same edges, five levels of machinery.
How Human Memory Works
One neuroscientist, one memory — a song heard at a party — explained five times over. A child watches the memory form; a teenager learns its real names; an undergraduate drives the encoding-depth engine; a PhD student runs a consolidation simulation; a peer argues standard model versus trace transformation.
Sorting and Searching
One professor, one shuffled hand of eight numbered cards, five audiences. A child drags cards into order; a teenager counts the comparisons; an undergraduate drives the algorithms in notation; a PhD student fits a growth curve to live timings; a peer argues about branch mispredictions and skewed pivots.
