This is EulerBeats. Imagine music as mathematical art on an NFT substrate. The Euler Record is a limited edition set of algorithmically generated art + music based on the Euler number and the Euler's totient function. Genesis (27 NFTs) and Enigma (27 NFTs) are two sides of the Euler Record. The EulerBeats smart contract extends the ERC-1155 Ethereum multi-token standard to create non-fungible unique original tokens and a set of fungible print tokens for each original. Both releases share a common mathematical basis, but differ in art, music, and bonding curve structures. Each original NFT has a limited set of prints priced on a bonding curve. The token is the art piece in itself. Everything needed to re-create each masterpiece is stored on-chain on Ethereum. EulerBeats is a careful and creative ensemble of math, art, music, royalties, instantly liquid tokens, and scarcity into a neat digital pack. It’s a first of its kind.
