A particularly interesting take on this is tailspin, although the repo appears have been taken down: https://github.com/wthimbleby/tailspin
That one offered a reversible JavaScript debugger written in JavaScript, which I thought that was very impressive from a technical standpoint.
I like this kind of stuff.
