During his time as Captain of the Gryffindor Quidditch team, Oliver Wood used a number of diagrams to show new manoeuvres and tactics to his team. These diagrams could be animated with the tap of a wand to further showcase the moves in question. Sometime before his graduation in 1994, Oliver Wood attempted to teach Harry Potter the Wronski Feint via these diagrams. However, Harry compared this attempt negatively to seeing the move in person at the 1994 Quidditch World Cup final.
