The Sporenspiel, a spore-activated glockenspiel
This shows an early incarnation of the Sporenspiel, a glockenspiel which is automatically played based on the amount of spores falling from a mushroom in real time. This video shows the Sporenspiel being played from a video file of mushroom spores, but it will eventually be triggered by real life mushroom spores. [Thanks, Adam!]
