How Are Emoji Made?

Happy World Emoji Day! If you look closely at the calendar emoji, it reads July 17 (at least on most platforms), a date that is now marked as a celebration of pictorial messaging. But who decided we needed a calendar emoji at all, as opposed to, say, a shrug or bacon emoji, both of which do not exist (yet)?

An international non-profit called the Unicode Consortium—with members like Google, Adobe, and the Indian government—is the final decider of all things emoji. Unicode is the reason you can send someone a smiling poop or a purple eggplant, regardless of whether you’re texting from an iPhone or an Android, though the images might look slightly different to someone using a different device and software than you. 

The beginning

Emoji were introduced in Japan in 1999, but each phone carrier encoded the graphics in different ways, leading to some confusion—a person might text a friend a thumbs up, only to have it appear on a different phone as a thumbs down. And when Japanese users tried emailing emoji to non-Japanese-hosted emails, like Gmail addresses, the messages would get mangled. 

Unicode is how computers represent text. Instead of having to standardize fonts and text sizes and alphabets and symbols like the plus sign so that they can be read on all devices, characters are represented by a set of standard codes, which software on your computer or phone (no matter who your email provider or phone carrier is) reads and translates into the text you see.  

Google was a main force in standardizing emoji, because in 2007, the company partnered with the Japanese telecom companies that had pioneered emoji in the mid-'90s to adopt a standard code in order to bring the graphics to Gmail. Emoji were added to Unicode. In 2011, Apple added an emoji keyboard to iOS. 

In the process, the poop emoji almost disappeared, because the head honchos at Google felt a steaming pile of poop was sort of an offensive symbol. Luckily, a few key engineers showed them the error of their ways, and the poop survived, and thrived (especially in Canada, as it happens). 

Introducing diversity

Unicode mandates that most emoji be represented as gender-neutral, except for a specific set of emoji that include symbols like “man and woman holding hands,” “bride with veil,” and “man in business suit levitating.” Why can’t a woman in a business suit be levitating? No idea, but as of right now, them’s the standards. 

This year, the first racially diverse emoji hit the scene, replacing light-skinned default emoji with a range of skin tones. According to a Unicode Consortium report, emoji were intended to be generic, but, thanks to their Japanese origins, they typically ended up with light skin. Now, emoji code provides for five skin colors, based on a dermatology standard called the Fitzpatrick scale

However, software developers design their own images to correspond to the code, which is why Gmail’s emoji look different than Apple’s. The Unicode Consortium recommends that when designing emoji, default options for human skin appear as generic, non-realistic colors, like yellow, blue, or grey. The Consortium also recommends dark hair, because it’s a common hue on people of every skin color. 

New emoji

There are currently 38 new emoji on the table for release in the near future, including the aforementioned shruggie emoji. But, should you find your emoji keyboard constraining, you can submit new characters for consideration to the Unicode Consortium here. The group considers factors like whether the new emoji will be compatible with existing systems, whether the pictograph in question is expected to see high usage, and whether it’s distinctive enough from other emoji that people will be able to recognize it. The group has hard and fast rules excluding any new emoji representing deities, company logos, and specific individuals. 

But why should an international group like the Unicode Consortium bother with emoji at all? Do we really need to insert engorged purple eggplants into our communications? 

Well, yes. “In social media, emoji make up for the lack of gestures, facial expressions, and intonation that are found in speech,” as the Consortium wrote in a recent report on the pictographs. “They also add useful ambiguity to messages, allowing the writer to convey many different possible concepts at the same time.” In short, emoji allow us to fill in the gaps where pure text communication fails, better approximating a face-to-face conversation.

Bob Ross’s Happy Little Menagerie Is Getting the Funko Treatment, Too

Back in August, the pop culture-loving toy fiends at Funko introduced a happy little Pop! Vinyl figurine of beloved painter/television icon Bob Ross, decked out in his trademark jeans and button-down shirt with a painter’s palette in his hand and his legendary perm (which he hated) atop his tiny little vinyl head. This Joy of Painting-themed addition to the Funko lineup proved to be an instant hit, so the company added a couple of additional toys to its roster—this time incorporating members of Ross’s happy little menagerie of pets, who were almost as integral to the long-running series as the painter himself.


Amazon

If you’re looking to score one of these toys before Christmas, it’s going to have to be a limited edition one—and it’s going to cost you. In collaboration with Target, Funko paired Ross with his favorite pocket squirrel, Pea Pod, which will set you back about $40. For just a few dollars more, you can opt to have the happy accident-prone painter come with Hoot the owl.


Amazon

On Friday, December 8, the company will release a Funko two-pack that includes Ross with a paintbrush and Ross with an adorable little raccoon.


Amazon

If you’d prefer to save a few dollars, and are willing to wait out the holiday season, you can pre-order Ross with just the raccoon for delivery around December 29.

So many happy little options, so little time.

See How to Grow Snowflakes Inside a Soda Bottle

While it's too soon to know what the real chances are of having a white Christmas, even if it's 70 degrees and sunny, there’s still a way to experience the seasonal beauty of snow without ever having to put on a winter coat.

In a video for Science Friday, Caltech physicist and snowflake expert Ken Libbrecht illustrated how to grow snowflake-like ice crystals inside a two-liter soda bottle. To start, you need to assemble your materials. Most of the items—including a plastic bottle, bucket, sponge, fishing line, paper clip, and pins—can be easily found around your home. The most important component, though, is dry ice—which also happens to be the hardest one to find (Libbrecht recommends checking your local grocery store).

The dry ice goes around the outside of the bottle, which is outfitted with a string hanging from a wet sponge on the inside. The warm air around the top of the bottle, where the sponge is, creates water vapor, which crystallizes around the string. Within an hour, you'll have cultivated a large, feathery crystal in the center of your makeshift snowflake machine.

Even though the final product resembles a snowflake, it's technically frost (snowflakes form in clouds from thousands of water droplets, not from vapor). Libbrecht has been growing his own snowflakes for years, though the system he uses in his lab is slightly more sophisticated. After learning how to grow a snowflake at home, be sure to check out some of Libbrecht’s own exquisite creations on his website.
