Explore the land of Neradia and meet the snowflake named Arenh Jerrus of Bosmen in the wintertime tale In Silico Flurries: Computing the world of snow,
a Scientific American "SA Visual" story about beauty, imagination and machine learning by Jake Lever and myself.

It's Snowing in my CPU — a Snowflake catalogue

Now she was round and as pure as the morning light, crystal clear and like a tiny silver mirror she was able to catch and give back every colour in the world about her.
— Paul Gallico, Snowflake

Go ahead, meet some snowflakes.

Somewhere in the world, it's snowing. But you don't need to go far—it's always snowing on this page. Explore light flurries, snowflake families and individual flakes. There are many unusual snowflakes and snowflake family 12 and family 46 are very interesting.

But don't settle for only pixel snowflakes—make an STL file and 3D print your own flakes!

Ad blockers may interfere with some flake images—the names of flakes can trigger ad filters.

And if after reading about my flakes you want more, get your frozen fix with Kenneth Libbrecht's excellent work and Paul Gallico's Snowflake.

This page uses code contributed by Alexander Pruss to generate an STL file for any of the flakes in the catalogue. The code is now hosted here to cross-origin requests.

authentically-grown flakes for your tree

Here is the 3D printed snowflake morptel. Yes, they all have names—snowflakes are people too.

Snowflake to STL conversion

It takes about 10–20 seconds to generate the STL file. You are about to generate STL for snowflake lomea (shown below).

To generate STL for a different flake, browse to the flake's page and click the Generate STL file for 3D printing link in the section SNOWFLAKE FILES AND RESOURCES.
