A mushroom plays the piano

This is a mushroom playing piano in the woods near Glossop, Manchester. Connected sensors measure the mushroom's biosignaling—its bioelectrical vibrations. These vibrations are converted into signals that control robotic arms. The entire system interacts with a synthesizer in Ableton Live, which plays music through a keyboard. And most importantly, remember that the chances of encountering a mushroom playing the piano are small, but not zero.
