Lev Termen's First Theremin

Origin
Lev Termen, AKA Léon Theremin, was a Russian inventor and physicist who is noted as the inventor of the theremin, the Great Seal bug, and the concept of video interlacing. He was also a mechanical engineer and served during World War I and the Russian Civil War. The theremin was the first mass produced electronic instrument, and was demonstrated in European tour in 1927.

Effects
Playing the theremin causes interference with any electronics in the surrounding area. Low notes cause only minor interference, but high notes have the potential to completely shut down localized power. It also has the added effect of causing lights to change colour depending on the pitch of the theremin.

Collection
During an exhibition in California, attendees noticed strange electronic interference in the building hosting the exhibition, as well as the lights seemingly randomly changing colour. Eventually, the entirety of the localised power in the building shut down, without any indication of an actual cause. The theremin was cleanly snagged after a short search, due to the building being evacuated.
