Encountered these miniature wood marble runs in Switzerland. Still on my “wish list.” Sounds like you may enjoy them, too.
Sticking to the magnetile theme of the OP, my kids and I have spent the most time and most occasions playing with the mangetile marble run kits. It works so well.
Very cool. I live in the US though. How can I order it?
Thank you.
That gets you into the marble run world... which is segment of YouTube... and there are some very impressive setups.

As an aside, there's an app out there is an app for the iPad called "Cuboro Riddles" which is a "how do you make the marble go from here to there using the blocks." Given that there are multiple ways that a block can channel a marble, this is a tricky one.
... and then if you get this over into the lego domain (not as "just something to fiddle with..." it gets you into the GBC. There is a standard for how one connects to another described at https://www.greatballcontraption.com/wiki/standard ... and then at lego conventions people hook them all up. https://youtu.be/avyh-36jEqA
