some recent photographs

Here are some items which I have photographed over the last few days.

bio-paper star twist

bio-paper star twist

An old design of mine, folded from a sheet of my bio-paper. the diagram for this work is available in this PDF.

Voronoi Tessellation

Voronoi Tessellation, detail

A Voronoi tessellation, folded from random points. Generated with pen drops to create the initial state.

stacked triangles, reverse

The reverse of my stacked triangles pattern, demonstrating once again the dual nature of tessellation geometry. I like the simplicity of this photo.

I owe a long write-up on the bio-paper process that I have been developing over the last several years, but that’s still a ways off yet. More on that to come as the spring progresses and my fermentation room warms up so I can grow more paper.



  1. Hi Eric, I really love the Voronoi tessellation but can’t for the life of my figure out how you did it. I understand how the pattern itself is created but how can you work this out on a single piece of paper whilst still allowing room for the folds in between??

    Hi Phoebe,

    I hope to document the folding process for the Voronoi tessellations sometime soon. It’s not complicated at all, just a little tedious… but then again folding tessellations is not an exercise for the impatient, right? 🙂

    Hi! I accidentally came to this website and really loved this voronoi tesselation. Is there a way you can tell me how to make it??
    Thank you in advance!! =)
