I'm installing Tiger on my laptop already. In fact, one of my players has already gotten into the act, creating a Deshboard widget to roll dice. I'm looking forward to the potential for gaming for dashboard more and more.
Of course I can share it... it worked out fairly well.
All I did was take the dice roller that I found on WotC's website (http://www.wizards.com/dnd/dice/dice.htm), and turn it into a widget.. no problem. It worked really well when I used it last night, expecially for those 10d6 dice rolls.
