Elasty When I upgrade to an iPhone 5 next month, I’m not going to get a case. I like showing off a beautiful piece of technology. Elasty, a new case concept from Yoori Koo, might change my mind. It looks painfully practical, even if I imagine it will stick to the inside of my pockets. It’s something I would use if I was going for a run or didn’t want to bring a wallet. [via Kenyatta]
