Hello! It's very nice video:) I am very interested with your website, 'mechanical toy' and I wanted to read your books. So I purchased your pdf books, 'Simple Automata' and 'Automata' with my credit card. But, I couldn't get any instructions or download link. I want to know why I can't download them. I couldn't find your email or something that I can contact with you, so I write on here. I'm so sorry for unrelated comment here..
