Google Googles can perform neat tricks like solving Sudoku as well as performing image-based searches, but for now it only runs on mobile devices. However, you can access an archive of the pictures you've snapped in Goggles online.
Google Operating System points out that if you visit www.google.com/goggles/history (and you're signed in to the same Google account used on your device), you'll see your images from Google Goggles. You can't use actual Googles features (so no solving Sudoku even if you've snapped a picture), and there's a warning message which suggests the archive might eventually disappear, but it's an interesting oddity.
