A large pattern with funky shapes and form. An original. Sort of origami-ish.

Wasn't satisfied with the original's colouring. Too much component transfer and colormatrixes yet the results are lacking a bit. So this time it is a simple black to transparent fade, making it possible remixing easily once there will be other blending modes supported as well. Probably in inkscape 0.92.

There are quite a few grid patterns, but this one is a super tiny grid with some dust for good measure.
