Spike Dome, designed by Aurélien Vermont

Today’s model is a tessellation that I folded at the Geometric Origami Convention in 2024.  That means we folded it within an hour and a half, not counting precreasing.  Very nice design, and potentially adjustable.  In principle, you could make spikes with any number of points, and have them spiderweb across the paper as you please.  For example, Aurélien has a model with the big dipper.

Personally, I look at these spikes, and I want to make them spiral!  Not sure if it’s possible within the design.
