We created an image recognition API (www.recognize.im) and it would be awesome, if you could help us with testing. :)
An example of what you can do with it: http://www.youtube.com/watch?v=K57Q-LVE1XU
If you are interested in testing, please contact me: firstname.lastname@example.org
For giving us feedback everyone will get the premium account for 30 days (also we'll have some other gifts for the most involved testers).
