The video opens with a train, a platform and a flash of light, the thought experiment Einstein used himself. From there it draws the two consequences everyone has heard of and few can picture: a moving clock ticking slower, and a heavy mass curving the sheet that planets roll across. Every object appears exactly when the narration names it, so the diagram grows at the pace of the explanation.
The script was written by the built-in writer from the single line 'explain Einstein's relativity', then storyboarded into fourteen-second boards. The boards were illustrated in the Creative style, narrated by a synthetic voice, and rendered stroke by stroke with the drawing synced to word-level timestamps. Nothing was edited by hand afterwards.
