Emoji started with a single heart you could add to the end of a message on pagers, and evolved into a set of 176 icons from NTT DoCoMo. That’s grown to over 2,500 symbols with version for our smartphones and computers, along with a movie that literally no one should ever have to watch. Now there’s a book from Standards Manual exploring DoCoMo’s original emoji and the impact they’ve had around the world. These are the same people that made the amazing NASA and New York City Subway style guides, so this new book should be pretty amazing. It’s a Kickstarter project right now and for US$65 you get the book, and the companion app.
