GoKawiilDeveloper builds a working ray tracer using only Brainfuck
A programmer wrote a functioning ray tracer entirely in Brainfuck, the minimalist esoteric language with just eight operations and a single tape of byte cells. The project, named rayfuck, was inspired by a CMake documentation aside noting that ray tracers have been implemented in CMake's own scripting language, prompting the author to attempt an even more extreme example in BF. The source code has been published on GitHub under mTvare6/rayfuck.
