Caffeine (Springy Unit)
Revisiting my Springy Unit, a design from more than 10 years ago, I realized it would be perfect for folding models of hydrocarbon molecules and aromatic com...

Hexagonal Honeycomb II (SBA-15)
I designed this model for the cover illustration of my father’s book on nanoparticles. It represents the structure of SBA-15, a type of mesoporous silica. My...
DNA Replication
My modification of Thoki Yenn’s DNA model. Folded from a long strip (1:8 or so) of metallic paper.
Crystal Structure of Gibbsite
I designed this model as cover art for Surface Charging and Points of Zero Charge, a book by my father, Marek Kosmulski. It is a reference work in electro- a...
Hexagonal Honeycomb
This structure can be extended indefinitely to fill the plane with a hexagonal pattern. By adding more layers it can also be expanded up and down.
