Umulius, by Thoki Yenn
Today I present a very small model called the Umulius. It consists of three rings interlocked in a Borromean Ring topology. That means that if any single ring is removed, then the other two are no longer linked.
The instructions for this model can be found online. It's a bit unusual in its design though. Typical modular origami uses mostly flat units, linking them together to create three dimensional shapes. But in this model, each unit is inherently three-dimensional.
This was a favorite among my Facebook friends for some reason. Someone pointed out that "Umulius" is Danish for "fool". This makes sense since the creator is Danish.
