Launching Rockets Origami Tessellation
Basically, it's just rectangles folded across a square grid. The rectangles bisect the gird lines rather than following them.
It's just one of those interesting patterns that was hiding in the paper waiting to be found.
I consider this first pic the front.
But the other side is a pretty compelling pattern in its own right. It kinda reminds me of a tile floor or a stone patio.
Pretty straightforward to fold assuming small intersection folds are not a problem for you. I use a blunt point metal nail file to help with difficult and/or small creases.
