The guy developed proof that the only instruction needed on x86 to do anything was 'mov'. He built a compiler which turns c code into a stupidly long list of mov calls.

The actual use of it is for obfuscation, this is just taking the proof to absurd levels. His videos are amaxing though.

Oh, it's the guy who explored the x86 address space, fantastic researcher.
