This triggers search
Basic facts of this person:
How strange that a doodle in honor of a Hungarian-British 1971 Nobel prize winner (physics: holography) appears on Google.com.hk, the Hong Kong HQ, triggering a search in Mandarin [available also in 中文（繁體）and 中文(简体) language versions].
It's worldwide, not just Hong Kong.
Google also added a way to see the doodle if you have a custom background (with the white logo). A simple button at the top right of the logo, admitedly I had to hover over it to see what it was.
Yes, today it's global already
