EZ Tessellation - Evan Zodl
This week we have Evan Zodl's EZ Tessellation. Nice wordplay.
You might say these are full diagrams for a simple tessellation. Sorry Evan, I had no need for a tessellation with your initials :) That is one of the cool features of this design. Its customizability. I've changed it to the initials OW for Origami Weekly.
You can also fold up the panels in the back similarly.
For a neat effect, try rotating the paper before pulling up the panels, and instead, bringing them down.
It looks pretty cool backlit too, but you need to do the mirror image.
