Adobe Air: Bookmash is an Adobe Air application combining over a dozen search tools covering video, music, photos, news and social networks you can search at once for new media material.
Bookmash has a Cover-Flow-like interface, similar in functionality to previously mentioned PicLens (renamed to Cooliris). You can search wide open, covering sites like YouTube, Dailymotion, Metacafe, Lastfm, Seeqpod, Flickr and more, or you can narrow your search based on the type of content you're looking for.
You can also add RSS feeds to Bookmash and media and articles from your feeds will become part of your searches. All the media you find can be easily bookmarked, downloaded, or shared with your friends via the simple menu available when you look at your search results in the detailed view.
