Advanced Lawnmower Simulator is a ZX Spectrum classic. Originally written by Duncan MacDonald, writer for Your Sinclair magazine, as an April Fool, it has become a mission for people like myself to port it to every machine in existence.

Personally, I've written versions for a Casio calculator, the Nintendo Game Boy, the Nintendo Game Boy Advance, the Amstrad NC100, and now the PICO-8 "virtual" console.
