Today I've noticed that there are couple of changes to the Google. I think this is not a April fool prank any more, but quite possible they are testing. Here are the list of things changed.
1. Search box is not a plain text box any more. It looks 3D and light gray colour.
2. Search text is blod.
3. All the other links at the bottom is bit lighter as well.
you can notice lot of changes to the search result as well.
1. Add Auto Detect location and you can change the location as well.
2. Colorful icons to switch between image, video, news and other searches.
3. Advance search is available only after you search something.
There are couple of more cool changes that Google is trying.
