It's Snowing in my CPU — a Snowflake catalogue
She was all stars and arrows, squares and triangles of ice and light, like a church window; she was like a flower with many shining petals; she was like lace and she was like a diamond. But best of all, she was herself and unlike any of her kind.
— 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 random 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.
Show a random flake or a random flake from this family.
