Woo I really liked today's tessellation, called Wobbly Pyramids! It looks the same on both sides (it's actually mirrored). To achieve this, one has to fold twists on both sides of the paper: it was my first time doing that. It comes with a new kind of challenge: making sure that the paper that you need on one side is not stuck on the other side, and it requires a bit of planning. That was fun! And I really like the backlighting of this one :)
4/25
The backlighting which is very busy! Full of tiny lines and triangles
The reverse side, which is exactly the same as the front side, but mirrored.
A yellow origami tessellation. It has three groups of three triangles touching by their points.
