Hi Joanna,
for some reason, the comment I wrote a couple of minutes ago was not posted (so perhaps it will show up twice later!).
Thank you for the nice example. I liked the idea of dragging the microphone and the use of states and especially the changing expression of the characters (much as Linda wrote before). I also liked the idea of the "orderly discussion" in the second example.
Two small recommendations:
1. In the "orderly" example, I was missing a visual cue on "who wanted to say something". I would occasionally drag the microphone to somebody, and it would snag right back because that person "had nothing to say right now". Alas, no feedback on who wanted to say something was given (or I did not notice it), and there was no explanation (e.g, a surprised character saying "I did not mean to say something...?").
2. In the same vein, I think it might be interesting to give each character a microphone and add a green/red "requests to speak" dot (much as this is often done in panels or parliamentary sessions). This way, the order would be clearly indicated and the "guessing" is reduced (unless this guessing is what you are after). Also, you might give the users some learning chances by letting them choose "who goes next" if there are two or more red lights lit at the same time (perhaps explaining aspects like "session chair can cut in" or something similar).
What do you think?
Keep up the good work, and keep posting it!
Guido
