A fixed-length string of characters computed from data by a hash function. In on-chain generative art, the hash of each mint transaction seeds the algorithm, so every output is unique.
With generative art, specifically, it explores the role of the random number generator in computing and the way that in long-form generative art the hash informs what the work ultimately becomes.

A collector had to cause the transaction. This transaction hash had to be used for the generative art piece to exist.
