Google has released another playful way to explore search results, this time offering a different perspective on pictures. Type a search into Google Image Swirl and you'll return a series of image stacks made of pictures that are similar both in a visual sense, but also in a semantic sense, meaning that it could be an excellent way to sort out results that are confusing, such as typing in "pirates" and getting results for a football team or apple and getting a computer company. A quick glance at the stacks will tell you which collection has the meaning you're after. Once you've chosen a stack, it'll open up into a swirl, sorting the results again into sub-groups that surround the original, and again after that. The idea is to help you quickly find the right image you're looking for. It's certainly works fast and would work really well with a touchscreen.
