They took the basic idea of Scratch, then made it into more of a game with levels, each level being a puzzle to (implicitly) teach or test programming concepts. As you progressed it'd introduce new syntax, while slowly "fading" more familiar syntax towards actual JavaScript code (though retaining the block/GUI-based interface).
We did some more work on further iterations but I'm not sure what became of it all.
