I might be the last person to realise this, but if you just add the broadcast green flag (which you get by shift-left clicking on the drop-down arrow) to top left of your project - you can save yourself a lot of mouse movement when editing projects
When I saw the title, I thought you were doing something with the webcam and AI, but this is cool too. Yet to try it out...

You know you could do, instead of
[scratchblocks]
for(row) = [1] to(length of (galaxy)::list)::control
...
end
[/scratchblocks]
[scratchblocks]
for each(row) in (galaxy)::list
...
end
[/scratchblocks]
yes 
It's to get around an issue with blocks in the for each loop having empty slots getting auto-magically filled
To see the issue - run these two to compare what happens
Hm, right-clicking the dropdown arrow doesn't work for me. I think you have to shift-left-click it instead.
It also works if you enter __shout__go__ into the message box.
