How to Make a Kotlin Series of Books

I want to make a big series of books and the fun thing I'm working on is that I want their covers to make this nice shape. So you might know that each of my book is having this regular shape and each of those shape will be moved a bit. But yeah, good luck on that. We are out of time. It's been great having you, Marcin. Thanks for all the work that you're doing in educating folks in the Kotlin community.
