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.
