oSkope visual search

oSkope is a visual search engine which provides searchers with access to images (fairly obviously), but also finds images from various sites and collates them. So it's possible to see all the book covers in Amazon for 'Pride and prejudice' - or all the DVD covers come to that. It's fast and allows searchers to arrange images in a variety of ways - linear, in a pile, on an XY axis and so on. Hover over an image to get a larger view and click on it to go even bigger. Register to keep your own collection of details.

I really liked the ability to search ebay visually - it was really helpful to sort out exactly what I was interested in, and looking on Amazon was also just as easy. I started out fairly unimpressed with this engine, but the longer that I spent poking around the more I liked it.
