This is pretty cool, its called Proogle, I dont think it will "live" very long, once Google's lawyers get their claws out hehe. Its basically a Google rip-off, but the difference is it shows the PageRank for each search result. Pretty cool though! ;)
Also by the same guy is this other cool tool, the Link Popularity Checker. It checks 5 different search engines for how many links there are to your site, the search engines checked are Google, AltaVista, MSN, AlltheWeb and Yahoo.
Hmmm i feel another bookmarklet or 2 coming on hehe :)
