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.
flake families
Flakes are grouped into 50 families using k-means clustering. Families are ordered by the number of flakes in each family—family 1 has the largest number of flakes and family 50 the smallest.
The flakes below are random samples from each family.
