I want to share these two amazing search tools:

The first one is an awesome song lookup search engine. Ever had that tune stuck in your head and not being able to remember the song ? Just tap the rythm into this cool web application and it will try and look up the song for you!! Okay I admit that the database that the site uses is far from covering all the songs but if it is one of the popular songs the chances that you find it are really high!

Next is a reverse image lookup. Pretty useful if you have an image and want to trace it to its origin. Although I have not used this much but I did try to lookup random shots and tried to look them up with success! So happy reverse searching!

If you know any other useful outside the box search sites let us know by posting them here.
