So yesterday, I was chatting on a developer e-mail list about how you can use basic statistics to find the most prevalent color in a camera frame.
One thing led to another, which in my case meant sample code followed by -- hey, this is kind of cool. Maybe I should put it in App Store. (Thanks go to Roland Gröpmair, who provided me with the on-screen buttons you see on the screen shot.) Which then led to a flurry of coding, submission to app store, and chatting with some dev buddies on IRC afterwards about how I built this thing.
