Link: Cluuz. is a visual search engine that provides results in a variety of different ways - via networking chart with links between concepts, in clusters or lists. It comes up with some very odd stuff - it was really keen to associate my name with the term 'young person excluded' for some reason I couldn't fathom. It's using the Yahoo and MSN databases from what I can tell, but not doing a great job of it - paying rather too much attention to photograph sharing sites for example. May be of interest if you like your results in a visual format.
It seems to be the month of visual search engines, and searchCrystal is the latest in the line. Now, I know that I've been less than charming towards these things, but by the law of averages one of them has to come along that I quite like, and I think this is it.
It's a meta search engine, and searches GYMA and (interestingly) Exalead. That's in the web search area. It also searches images (which oddly is the default - if you're trying it for yourself do remember to change this or you don't get what you expect), blogs, video, news, Wikipedia and a few others besides. Imagine a series of concentric circles, put results from search engines into different sections and the more times a particular site is found the closer to the 'bulls eye' it gets. Now add in some little coloured icons to illustrate which search engines have found which sites, and you're almost there.
You can change the format of results into the normal linear display, or onto a spiral and you can also change the size of the font, which I think is really necessary, since it's rather a small, cramped screen, and it's really very difficult to read. To be honest, it's not a search engine that I'm going to use, since I don't like this sort of display. However, it's by far and away the best of this type that has come to my attention, and they also provide a handy little widget so you can try it yourself. It should be embedded below.
Link: walk2web - Walk. Explore. Have Fun ;). This isn't a search engine as such. What it does is allow you to type in a URL and it will then display links from it. You can move along the links, see more of them, reposition the map on the screen. Much fun.
Quintura has relaunched and is sporting a new and better design interface, much better than the last version. However, while it's improved in that area it still requires some more work to bring it to a stage where I'd want to actively consider using it. My full review is over at Search Engine Land.
