Sorry if this has been posted already.

Apparently Google’s actually been testing a “new” Google look-and-feel for its search results.

"So who sees the changes? About 1% to 3% of Google users, who will be randomly selected. The test will probably run for about six weeks. If successful, expect to see the changes — altered to take in account test feedback — show up across Google soon after that."

I guess I was in the group of that ones who see it.
