Google has a bunch of hidden easter eggs in Chrome OS. Here is a list of easter eggs that you can try if you have a Chromebook.
Do a Barrel Roll
if you search Google for “do a barrel roll”, you will see the entire search result page will do a barrel roll. On a Chromebook, you can make the entire screen do a barrel roll using this keyboard shortcut:
CTRL + ALT + SHIFT + RELOAD
Chrome Logo Spin on Chrome OS Settings Page
Open your Chrome OS Settings app. At the top of this page, you will see a Chrome logo and the words “Google Chrome OS”.
Click this Chrome logo and you will see it spinning.
Do you know about any other Chromebook (not Chrome) easter eggs? Drop me a comment and I will add it here.
