I wrote a ray tracer in Brainfuck

A developer wrote a ray tracer in Brainfuck, an esoteric programming language with only 8 operations, as a challenge to demonstrate that complex algorithms can be implemented in extremely simple languages. The project involved representing complex data types like doubles across multiple cells on Brainfuck's infinite tape and rendering an image using only increment, decrement, loop, and I/O operations. The developer intentionally avoided looking up existing implementations, instead building the ray tracer from first principles to test the language's capabilities.
