Artist Dr.Bks Varma shows off a remarkable drawing technique, in which he takes a cotton thread saturated in india ink, and uses its tip to draw solid lines, and its edge to create feathered shading. Watch him create another string and ink portrait here.
If you take a felt tip marker and whip it fast enough, some ink will come out and create a spatter. The Slow Mo Guys decided to take this idea and amp it up by building a multi-pen spinner rig for a power drill, then let the ink fly in front of high-speed cameras. It’s a great way to make modern art too.
