Have you ever played the game Farkle? Yeah, me neither. We've been using UIKit Dynamics to create a version of the dice game. We had to add the shake gesture recognizer so when the user shakes the phone, the dice are thrown around. You select dice that are worth points and then you roll again. It's not where it needs to be quite yet, but my partner Logan and I got it to look a little something like this.
We also got into the Meetup.com API. Using API's and dissecting it's data to show users the right information is very important. I hope to get some time to dig around the twitter API soon.
