IBM Seer beta
The IBM Seer beta is an application designed to help you navigate you way through a better time at Wimbledon. Point your phone at anything the app will tell you what it is. In camera mode what you're looking at and what's happening there now. For example, concessions reveal themselves to you and then tell you how long you can expect to queue. Check out screenshots of the app in action.
