Community Dominos and Launcher?

So Rob has been attending group meetings with 4-5 other patients and at this particular gathering it was decided to play dominoes. Rob was on an arm sling with his dominoes on a tray in front of him, when it came his turn he would attempt to swing his arms and either touch or indicate the domino he wanted to play. One of the therapists said Rob needed a domino launcher, and the head therapist said good idea you have 5 minutes to make it, and he was off to construct.

You can see the resulting launcher in the video below.
