This appears to be working demos of the ideas that Bret Victor brought up when he initially criticized Khan Academy's CSE program -- the ones mentioned at http://worrydream.com/LearnableProgramming/.
I feel like the OP is missing the forest for the trees; the key takeaways from Bret Victor's lamenting seemed to indicate to me that we need Yet Another Programming Language, but one that non-programmers can actually use for "real programming" in conjunction with a "real IDE" (as opposed to one where you just "learn programming" but don't use for "real work").
