the insult machine - electronic brick version

how it works:
on the first “insult machine”, using the potentiometer (Analog 5), the user scrolls through a list of potential 2-line insults on the 16*2 LCD (BUS 2).
the button (Analog 4) is pressed once to choose an insult.
“You have chosen insult x!”
“Tilt to send”
the button (Analog 4) is pressed again and the insult is “sent” (Digital 9 - comOut) to the 2nd “insult machine” (Digital 8 - comIn)…
“INCOMING INSULT!” flashes on the LCD (BUS 2) of the second machine, interrupting the 2nd user.
the chosen insult is then displayed on the LCD (BUS 2) of 2nd machine followed by computer laughter (HA HA HA HA in random positions alternating between the first and second row of the LCD).
both users return to scrolling through their respective insults using the potentiometers (Analog 5).
i uploaded a slight variation to each machine: machine one has 10 possible send insults and ten possible receive insults, machine 2’s libraries are reversed so the insult you receive is not in the list you have been scrolling through). i change the comebackStrings[] called up in the code and upload to the 2nd machine.
