Android developer Ryan Bateman posted this hilarious video of two motion sensor trash cans setting each other off in an infinite loop. According to Bateman, his father (who can be heard laughing uncontrollably in the video) is the mastermind behind the trash can loop:
Day 1: Father discovers bins with sensors that trigger when he walks by, laughs every time. Day 2: Dad begins greeting bins as if they were loyal, eager dogs. Day 3: Dad creates infinitely triggering bin cycle, laughs ass off.
