The Bubble Level or Spirit Level on Google

I told Search Engine Land last night that you can now turn the Google search results page on your phone into a bubble level (or spirit level). For example, on your phone, type [bubble level] or [spirit level] into Google. The search engine will then show you this live bubble that tells you how tilted your phone is.

Here is the GIF I made that shows it in action:

From what I can tell, this was first seen on reddit.

As I already said, this is not an Easter egg but a function. In a way, it looks more like a computer than a silly Star Wars hack.

Talk in forums on Google+ and Reddit.
