We developed Pairopix as an early test of app possibilities after the iPhone came out. A simple matching game where tapping the closed irises briefly exposed images to match as pairs against the clock. The game came with four standard images sets, but you could build your own sets from the iPhone's photo library or camera for a more personal experience. Eventually we built a commercial version and sold it to our client at South Bay Mini as a branded free game app with product image pairs.
