Click on the flag. Strum (click) on the guitar strings to make notes appear in random locations.
I started this idea for the touchng color activity. I was considering doinng a garage band kind of project. Then I decided to play with broadcast and the random blocks. I was trying to use the clone tool so that there would be a different not (not the same one changing to a different color), but it kept duplicating (not just making another note. I even used the delete this clone block to no avail. I am open for suggestions.
