ChessVid turns games from P. Wenman's public-domain collection of 175 chess brilliancies into narrated animated replays. The games are ingested as notation, validated move by move, then rendered with narration and timed sound rather than assembled by hand.
The interesting constraint is editorial: a replay is only worth watching if the commentary arrives on the move it is about, so the narration plan and the animation timeline are generated from the same source and checked against each other.
