Like with most Google features, I don't see it yet. Recently, a tip was posted to HN that showed Google having a timer that could be activated by a search command; another feature that simply doesn't work for me. I've tried both google.co.uk and google.com in Safari and Chrome.

I also see the UI switching occasionally from the black bar at the top to the cleaner UI that's in the picture.

Are they A/B testing or something? It makes Google feel very unreliable as almost nothing works consistently for me.

Yeah, it's being A/B tested. Some of my browsers have it and some don't, even after clearing caches.

My search page has been like this for weeks.
