Tried to make a simple looping note, pressed play and it hung my tab with an 'unresponsive script'. Nice concept UI, but couldn't make any sound.

The idea of the 'puzzle pieces' to show where to slot in components is very interesting though. Maybe, although my pieces stuck together properly, it was syntactically invalid? I would think that with the design such a system would prevent invalid programs from ever happening; quite an achievement IMHO.

Now if only I could get it to make some sound...

Ah, it's made with something called Blocky from Google. Very interesting interface paridigm. Thanks for doing something with it as an example.
