VideoWorldSearch.com is a simple, redesigned PR3 video search site powered by a script which uses the Truveo API to do its searches.
It looked butt ugly before, but I redesigned it into this pleasant blue look it has now which also has predefined ad places.
What could it be useful for you ask? Well you could have it as a complementary service to some other site you might have which might have something to do with videos, youtube and whatnot. You could build on the script to create something even better. Yes there are other video search sites, but yours could look and feel the best. You can put a blog to it and write about video marketing or something like that which would help promote the site. Or at the very least it's a place where you can put some free PR3 links to your other sites.
It can be yours for just $30 - the domain, the script, the design.
