Bitlisten is another interesting blockchain visualization website. For those willing to listen to harmonic melodies of the blockchain, Bitlisten is their ultimate website. It enables users to see visualizations of Bitcoin transactions in real time even as they listen to the sweet melodies. The melodies are made up of small bubbles representing Bitcoin transactions. Interestingly, each bubble carries a distinct sound and it gets melodic when a number of transactions happen at the same time. The beauty of this is you can change the pitch of the melodies made after transactions have been broadcast in the network.
