Domino Robot Trajectory Generation

Mark Rober had a nice video on this robot. To me, the coolest part was the 'refill station' they built to load dominoes into the robot.

One critique on the design is that it only does big boring fields of parallel domino reactions; it can do pixel-based art, but no curving or other patterns that even a child domino stacker uses. There's room for domino robot innovation!
