There’s a group called Flickr hacks which has some interesting things you can do with photos and more. I had posted an idea about using Flickr as a universal translator- you type in what you want to do, say, find, eat or whatever on your phone and you get a picture back that you can show someone you’re trying to communicate with. It’s based on a book called “Point to it“. Steeev from the group made a prototype which can found here. Neat!
