[Black/White] Square - Kim Asendorf

Kim Asendorf's "Black Square" and "White Square" are two generative on-chain works on Ethereum Mainnet in which opposing algorithms keep each square in constant tension between preservation and dissolution. Each piece is a 1/1 with a 1.0 ETH reserve price, and both are offered in auctions that run for 7 days and extend by 5 minutes when a bid lands in the final 5 minutes. Asendorf describes the pair as companion works, with the black square on white representing physical reality and its inverse representing the digital. The works are fully on-chain, with 11.5 KB of code and no external dependencies.
