Fall Down an Internet Rabbit Hole
Diatoms' theme was inspired by the real art of microscopic diatom arrangement after designer and publisher Sabrina Culyba fell down an internet rabbit hole about them. Why don't you follow her down with these links worth checking out:
- Secretive Victorian Artists Made These Intricate Patterns Out of Algae (includes the 5 minute film The Diatomist about Klaus Kemp)
- Klaus Kemp (1937-2022) in Memoriam (includes Wayback links to Kemp's website)
- Brief story of Klaus Kemp's life- worth reading!
- And the story of the Victorian-era diatom arranger who inspired Klaus Kemp, JD Möller

A Blend of Science & Art
Microscopic mosaics out of algae? Yes, they're real! Step into the world of Victorian naturalists, where microscopes revealed the unseen natural world. Collect and arrange glittering diatoms into mosaics that shine under your “microscope.” Petri dishes, a lens tool, and Field Notes bring the wonder of science to your table.
Fall down the science rabbit hole of Microscopic Mosaics like we did when making this game!

Unforgettable Table Presence
Extra-thick sparkly tiles, gorgeous goldfoil accents, ornate dual-layer boards, and included petris dishes all add luxe touches that make every play feel special and ensure Diatoms returns to your table again and again.
Each detail meant to delight you and pay homage to the fantastical beauty of both the natural world and human endeavors of art & science.
Build dazzling tiny mosaics out of algae and discover just how gorgeous (and fun!) the microscopic world can be
