Some parts are interactive, some parts aren't. This isn't supposed to be a fully functional Scratch in Scratch, it's just to give you an idea of what I think Scratch might have looked like on an old Macintosh or something. The blocks don't have labels because there is no way I'm filling out a gazillion black-and-white Scratch blocks. :P Maybe I have something to work on in the future, then!
Heavily inspired by old Macintoshes. Editor is mostly based on the 3.0 editor, but some of the design is based on photos I've seen of older versions.
