Not sure if this is where i'm supposed to post something like this but..
I've just finished a site which allows you to search Google, Twitter, Wolfram Alpha, and all at once.
Additionally the video search allows you to search and download from YouTube, Hulu, and Vimeo!
The image search searches from Flickr and Google Images
I thought it might be useful for many people, so enjoy! Tell me if you find any bugs too. Thanks
