This article might came a bit late, but I am so excited about Google Goggles, and it makes me want to buy an android phone even more! :D
Basically to use this ultra handy apps is just simply :
1. Take picture of EVERYTHING you want to know
2. Send it up to Google
3. Google will be back in a sec with an explanation! (or depends on how fast is your internet connection I guess.. )
Whether its a landmark you wanted to know more about, a painting you saw somewhere, a menu in French you'd like to know what it is and how to make it, and even a road sign in Chinese you're desperately needed to know what it says!
This technology is awesome! It's almost something like Layar I guess, but more developed.
In my opinion, you'll be as knowledgeable as the Wikipedia once you have this power tool in your pocket! ;)
