Penny's Money Lab

One calculation or comparison drawn on ledger paper. Every beat has a drawable callout: a counting number ('$698,202'), a face-off ('$500 VS $2,000'), a numbered move ('STEP ONE'), or a rule in four words ('RULE OF 72'). Open on the number that surprises, show how it is computed in plain steps with exact numbers the viewer can check, end on the one move to make today. About money mechanics, not people: no stories about real individuals, nothing that needs a photograph.
