Experiments at the edge of software, science & creativity.
A scratchpad for prototypes and demos from Frontiers Lab — an independent studio for ambitious technical work, AI‑assisted research, and product prototypes built by Adam Jesionkiewicz.
The Index
ZX BASIC compiler and emulator built in Rust, compiled to WebAssembly — running 8‑bit machines in the browser.
A full Apple Lisa emulator in Rust + WebAssembly — recreating the 1983 workstation, instruction by instruction.
