I never really shared this tool, but I used it in a few presentations quite succesfully, so I think it could be an interesting tool to use. You have full control of the speed. You can pause and resume... An entire app can be live-coded with this. It's quite fun to watch ;-)

There is a Demo in the repo, a bit slow at the beginning but wait until the end, gets better. Hope you enjoy it and please, feedback would be very much appreciated.
