Knot Structured

George W. Hart

This is a recent (2016) updating of a sculpture design that I first made in 2003. 
Here, the thirty planar components join with cable ties; the earlier version used glued joints. 

The ins and outs are fun to explore.  I like to follow the edges with my eyes.

The above video gives a good sense of its structure.

Be sure to observe that there are twenty of these trefoil knots to be found among the edges.

There are also twelve of these "pentafoil knots".  (And sixty "unknots" --- the circular openings.)

If you want to make your own version, here's the template. 
The edges need to be beveled to the angles shown (in degrees).
