Incredible tool let´s you search the web with an image

I found a really cool website that searches the internet using an image. It's like Google, but instead of typing text, you upload an image. So you can do stuff like:

• Find the same image but in bigger size
• Find out who or what exactly is in the picture
• See how the image is used
  
• See similar versions of it
  

Try Tineye with your favorite image and see what it finds!
