Introducing the latest Google product: Google Household™!
With this new product, Google can index your entire home, car, place of work, even a second home or boat and store what is in there on their servers.
With this handy search option (available at household.google.com) you will never lose anything again. Simply navigate to the page, type in your search, and Google Household™ will bring up a picture of the last place you left whatever item it is you are missing!
I managed to snag a screenshot of the search page
I also got a screenshot of an actual search (in my own home)
This product is still in beta testing and has not received official support. Also, due to high demand, the server hosting the Google Household™ page is often down and thus the search feature is unavailable.
