A reminder next time I'm tempted to go into the shop and do a half-assed attempt at something like Mathias Wandel's Modular Marble Machine but not get anywhere 'cause I've got stuff queued up and the kid who's goading me into this doesn't have the patience to set up jigs...
We could build marble machines out of paper (YouTube video of the paper roller coaster).
