Things, the Hands-On Encyclopedia of How Things Work

Field notes

The project combines manipulable models with short, sequential explanations that follow mechanisms from part to whole. Its visible examples range from a three-minute gear explanation to a seven-minute inline-six cutaway, with the latter naming six pistons, a counterweighted crankshaft, twin cams, and 24 moving valves. The page also says written explanations and references remain available without the JavaScript interaction, giving the material a readable fallback rather than making the models the sole route to understanding.
