A year ago, Japanese artists So Kanno and Takahiro Yamaguchi showed the world their Senseless Drawing Bot through a video of the machine spraying random, abstract paint onto various walls. While that was already a feat of brilliance, they've decided to come back with part two, two years later.

The bot uses a single automated arm with a rotary encoder attached to the pendulum, swinging with the help of inertia. It's a new way to create abstract graffiti, in a sense, and it keeps getting better.
