I have to find a way to use Emoji One on one of the (too)many projects I’m doing! I love it.
It’s the coolest set of emoji around, and free to use under Creative Commons License (CC-BY 4.0). You can read all about it at their licensing page.
Emoji expression represents the modern communication of today, as well as the future. It’s a privilege to share our beautiful expressions with the world.
