Where is the app from a few years back, where you pointed your phone camera at some text and it switched it with a translated version of it live in-picture ?

Not only did it look awesome, but it would also be a perfect application for google's glass. Imagine, you're in berlin, or tokyo, or madrid, you read the menu in a restaurant and you have the exact translation displayed to you live in the corner of your view ? Or in a museum, etc ..
