Long time ago (probably circa 2005), I've encountered an esolang that had two separate 'instruction wheels', and two possible instructions, and a brainfuck-like array with pointer as memory. The instructions were 'rotate the given wheel' and 'execute instruction and switch wheels' - kind of what Braincrash does to brainfuck, but with more instructions. The only instruction common to both wheels was NOOP. I think the language was turing-complete (possibly by a trivial reduction to BF).
Does anyone here remember such a language and has any resources on it?
