Previously seen letting mushrooms play a keyboard, Youtuber BionicandtheWires is back with another video, this time allowing a colony of oyster mushrooms to paint a picture. The mushrooms’ natural fluctuations in electrical activity is transformed into brush movement via attached solenoids. That painting, wow — way better than anything my nephew has ever done. Maybe next time he should employ a mushroom robot if he wants to take home anything but a purple ribbon from the middle school art show.
