As I noted last time, this is really, really similar to the Self environment (this demo makes it even clearer). More typing, but cleaner (Morphic isn't exactly sexy, and the Self environment's UI is quite messy and could be significantly improved I think — especially on OSX where you're forced to deal with Morphic itself and with the fugly and shitty X server).
I really think Self on iPad could be a nice beastie, it is way more visual and touchable than even an adapted text editor like Lisping (though not a visual programming environment)
It looks more like the structure editors of the 1970s adapted for a tablet. Mid/end 70s several structure editors were written in Lisp, for example DEdit for Interlisp-D.
