UPDATE (2018/09/23): I pulled this from the App Store and GitHub today, as it hadn't been updated for the iPhone X and later, and its code really wasn't an ideal implementation by today's standards. — It was cool while it was online, though! 😎
UPDATE (2016/02/16): This has also been open-sourced on GitHub!
During my parents' recent visit to San Francisco, my mother and I checked out the local Exploratorium science museum. — I loved some of their interactive visual displays, and was inspired to build a rendition of “Conway's Game of Life” for iOS that same evening.
It's a pretty simple simulation, but has some nice effects. Try shaking your device! 😉
It only took me a few hours to code, but boasts iPad support in addition, and of course a stylish “flat” design for iOS 7! It's available for download now on the App Store for free. 👍🏻
