So if you've enjoyed this course, I'd like to encourage you to keep exploring. Learning how to open one lock opens a door into a world full of incredible figures, just remarkable mechanical puzzles and big ideas that exist all around you that you wouldn't know where they are otherwise. I like locks enough that I'm hoping to do a couple more of these. Maybe cover some more advanced concepts and different locking mechanisms and some more esoteric stuff too. So if you've enjoyed this look out for those and even if those don't happen or if you decide that you'd rather learn other ways keep exploring there's just a lot of remarkable stuff out there. Hope that you've enjoyed it. Feel free to ask me questions.
