The much-awaited day has finally come: Google Goggles is Now Available on the iPhone.
Search for "Google Mobile App" in the iTunes app store and if you've got a 3GS or iOS4, you'll be able to use this incredible visual search technology. Take a picture of a landmark, a book, a bottle of wine or much more and you'll instantly receive Google search results about the subject of your photo. The availability of Goggles on iPhone was just announced minutes ago. See the demo video below. If you'll excuse me, I need to go run around and take pictures of things now, while jumping up and down and clapping.
Try taking a photo of a business card - if well lit, you can import the details into your phone's contacts list! What else works well?
