The new old theremin: Lydia Kavina at TEDxGhent 

Have you ever heard of the 'Theremin'? It is the only instrument which can be played without any mechanical touching! One of the first electronic musical instruments ever built, the theremin was invented by Léon Theremin. Playing this strange instrument is an art perfected by Lydia Kavina, a distant relative of Léon Theremin himself.
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
