I'm writing a book on Scratch, and looking for a project that creates a basic four function calculator. I've found a few nice ones uploaded on this website, but haven't heard back from the creators. If you'd like to send me yours and it works with the book, I'd love to include it (and of course, your name will get featured in the chapter with the project).
Also, I'm including a chapter on project remixing. If you have a project posted already that you think is good, and you'd be willing to allow me to include it as a project users download and change, please let me know!
My personal email address is email@example.com, feel free to shoot me an email!
