Zhoubi Stars Tessellation: Front
So named to relate to Oschene's Zhoubi Bowl... (diagrams for that found here: origami.oschene.com/archives/2006/08/05/zhoubi-bowl/)
There are creases in this tessellation that are folded at the slope of 1/7... Reason why? Well, because the difference between the slope of 1/2 and the slope of 1/3 is apparently 1/7... (easy to demonstrate via graph-paper)...
Perhaps the most intriguing fact about this tessellation is a comparison of the front and back. ALL edges on the front are at multiples of 45 degrees while NONE of the edges on the back are at 45 degrees.
