Did you know that your iPhone 5/5s has an accessibility function that causes the back camera’s flash to light up to indicate an incoming call? Combine that function with the Sparkbeats case, and you’ll have a cool, geometric incoming-call indicator. The Sparkbeats case simply channels the flash’s light, so it doesn’t require a battery of its own – meaning the case is sleek and light and minimal. The case is made of high-grade ABS with a fine textured surface to safeguard against daily wear-and-tear; it has a non-slip grip, too. There’s also an app that can make the case light up when you shake or move it, and it will also sense when you’re playing music and flash along to the beat. The Sparkbeats case for iPhone 5/5s is available in black or white for $49.99 from BiteMyApple.
