Thanks for letting me know 'Kids' community. This programming tool is Scratch (http://scratch.mit.edu). You could do anything in the web site. But some kids are difficult what to do how to to. That's why I make a short movie. I'd better to make new movie for starter to introduce the tool. Thanks again for your comment. ^^
Thanks for sharing, @JayKim797! This looks like a great tool for kids to learn programming in a fun way. Game design is such an appealing approach! You should post this to the "Kids" community as well. Could I make a suggestion, though? I'd love to know more of your thoughts about the background of this tool, how it works and why you like it in the text. I'm so curious about all of those things! Well, thanks again for sharing :) I can't wait to start doing things like this with my son in the not-too-distant future.
