Have you ever seen something and wish you could get more info in as snap (pardon the pun) or you see something and think WTF is that. Well there will be an App for that, namely Google Goggles.
It was only a matter of time before Google came out with a visual search product. Google Goggles is geared towards the mobile market and allows anybody with the ability to snap a photo to receive relevant information via Make Magazine
Now the question is how long will it take Google to catch up with other similar applications? Most services I have seen only does bar code scanning so Google is one step ahead in that aspect, seeing that you can search for any image, so if you take a picture of Big Ben in London or The Statue of Liberty it will return results based on that.
I can think of a plethora of uses for this, product reviews, history of places while walking, more info of say a Polar bear while visiting the zoo just to name a few. Here is a short video that demonstrates Google Goggles.
