iPhoneDevCamp was an excellent event. Thanks to Raven, Whurley and Dom for putting it together, we really enjoyed it. Over 51 applications were started or built over the weekend including one built by the Big in Japan team. We decided to build a tiny application that would use the ability the iPhone has to determine the orientation of its screen. Based on how you held your iPhone you would signify your agreement or disagreement with the speaker. We call it iPhoneVote and ironically it was voted one of the 'top ten apps' from the event.
Other cool applications included: AppMarks, PickleView, Fluther, The Pool, itunes Remote-o-Matic, Tilt and moPhaic (read about them here). The coolest hack from the event was called the Fluid Navigation Hack as described by Andrew:
Have you ever heard of Firebug? It's the absolute best Firefox extension for developers. If you are building applications for the iPhone, it might be your greatest debugging tool. But Firebug for the iPhone, iBug.js, is not my favorite app. It's Joe's liguid navigation hack. Almost 25% of all apps presented at iPhoneDevCamp used it. Hewitt's Javascript and CSS package mirror the iPhone's iPod application, and use a fluid navigation scheme that will become commonplace to any iPhone user. This is my favorite app because so many iPhone hackers used it this weekend as a backbone for their application. This framework will work nicely for future iPhone development because it's lightweight, elegant, and comfortable for anyone trying to navigate their Apple smart phone. The source code is available here. This would be my starting point if I were to develop an iPhone app.link to original post
