Mathcastles is a studio composed of two anonymous developers, 0x113d and xaltgeist. The duo is focused on creating a new runtime-art movement on Ethereum, beginning with their genesis series, Terraforms. In September 2022, they wrote both three.js and p5.js into Ethereum Virtual Machine (EVM) storage, enabling creators to use these libraries as composable tools in dynamic EVM-based work.Mathcastles exemplifies how two creative minds can collaborate to push boundaries and foster meaningful dialogue in the digital space.
