On this experiment, sand falls through set of points and forms a voronoi pattern. Similar experiments were done by Frei Otto in 1970s, and it was a great experience to work on it in person. I am currently in the process of experimenting with more complex patterns, instead of just using points.

I did some experiments with exotic 3D printing materials like wood and metal filaments. On this image, I had tested a Corinthian column in wood, after printing, it was sanded and stained. The result was really interesting.
