Open Firmware is definitely a highly polished work of love. Its well-commented and meticulously organized source code reads like fine literature or classical music! Stuff like the metacompiler and kernel, for example: https://github.com/MitchBradley/openfirmware/blob/master/forth/kernel/metacompile.fth https://github.com/MitchBradley/openfirmware/blob/master/for... https://github.com/MitchBradley/openfirmware/blob/master/forth/kernel/kernel.fth https://github.com/MitchBradley/openfirmware/blob/master/for...
