Sarah Petkus offers to let her robot lick Christopher's leg. Christopher agrees reluctantly once we determine the saliva will be anti-bacterial hand sanitizer.
Sarah is a kinetic artist and some of her projects include a robot army (built your own from parts printed out or purchased at robot-army.com), Noodlefeet, and Carl (the flamingo of pendulum inversion). Her Zoness.com site is an umbrella for her drawn and robotic art. Specifically, you may enjoy her webcomic Gravity Roads, her YouTube channel, and/or herRobotic Arts blog.
