A recent collaboration between social influencers Estefannie and Look Mum No Computer, the pseudonym of musician Sam Battle, has resulted in a device that creates sounds (or music, perhaps, to some?) based on the price volatility of various cryptocurrency markets.
Battle constructed a mechanism to generate voltage fluctuations as derived from changes in crypto price, and Estefannie programmed a Raspberry Pi to produce a sequence of relevant sounds from that data.
