Orbit, the cat
On each new tab, my cat will tell you how awesome you are.
I made this extenstion because I miss my cat at work. Added a ton of jokes (murphies laws, cat jokes and what not!).
If you're a cat lover, you'll love this chrome extension.
(PS: I've been trying to practice mindfulness at work, so this extension hasa nice little surprise that'll help you be more mindful at work)
