I got to try it out; a good start but still a bit clunky:
the layout+object adding is in HTML; the programming with jigsaw pieces bit
is a java app, which makes for clunky transitions back and forth.
The underlying typedness pokes through; the obvious thing to do (drag the
function parameter into a slot in a contained piece) doesn't work, but gives
a cryptic error. instead you have to go find the tab with the value of the
parameter in and use that instead.
Although the blocks are event driven, there is a tacit drive to global
variables for creating shared state; no obvious way to add a field to a
built-in element (unlike Scratch)
The 'hook the orientation sensor up to a rolling ball' idea idly mentioned
by one example didn't work; the sensors use degrees, the trig functions want
radians, the built-in 'ball' object has a velocity vector and a heading in
degress with a different zero point, and hooking up the trig with jigsaw
pieces is far from intuitive:
Also, there is no way to call a web service from an app except a kludged one
with a very constrained memcache key-like API, and a hard-coded twitter API
Overall, I'd much prefer something that compiled to HTML5+CSS+JS than this
thing that generates JVm blogs that can't be modified except by this editor.
