Accelerometer-driven reflection effect in iOS 6
An evolution of foursquare design from January 2009 - August 2011
One of the great things about working on one product is the ability to iterate; the bad thing is you never feel like you’re done.
When foursquare started there was no real visual design on the app. Naveen was coding it up alone and he used all native Apple UI elements. I was helping out on the side and slowly we added custom elements and branding and for SXSW 2010 we did our first visual pass at the design. At that point I was doing everything, and it showed. One person can only do so much. Now we have a talented group of UI and UX designers and these days I mostly work on the iOS app.
We just put out a new build complete with a new blue navigation bar, photos inline, single tap cells and a newly designed check-in detail screen. I’m really proud of this current iteration of the app and can’t wait to see it continue to evolve.
Andy Hertzfeld on Google+, UI design and how Bob Dylan influenced the Mac

Andy Hertzfeld worked on the Macintosh project at Apple after having been hired on in 1979 as Apple employee #435. He was one of the main authors of the system software and the User Interface toolbox.
After working at Apple, Andy left and founded three companies including Radius and Eazel. In 2005, Andy was hired on by Google. Over the last couple of years, Andy has been working on the Google+ project, bringing his experience in design to the Circles grouping feature.
Andy had a few minutes to talk to us recently and shared some of his insights into the design of Google+, including Circles, how that design will influence the rest of the Google+ project and, eventually, all of Google’s products. We even managed to sneak in some questions about the future of computing and user interfaces and got some interesting answers from one of the people that was there when consumers first got their hands on what would set the tone for the next three decades of computer interaction, the Mac.
Oh, and we talked about Bob Dylan and Steve Jobs a bit too.
