The other way around - Scratch is the original (though inspired by the earlier Etoys and other systems) and has become the standard to be copied by other block based languages (not counting those directly derived from it like Berkeley's Snap!). Pretty much like most new languages looked like Algol/Pascal until the late 1980s when they all started to look like C instead.
