I didn't see that anyone has posted about this yet here even though it appeared on installer yesterday. I downloaded (on a 1.1.2 phone) and it works great. I don't know how much I'll actually use this, but its kind of fun to kill time.
Yeah its a nice little App. Theres a thread over at MMI where the author launched this, you can post your requests and bugs there. I'd personally like to see a cue ball and crosshair section so that you define where you're going to strike to coax a little english onto the ball.
