Lego railway and through a house and garden [video]

This is fun to see and all, but what has this got to do with 'hacker news'? There is no in-depth information about how it was built, how it was programmed or something like that. It's not a new concept, this has been done a lot of times. The video isn't even new, it's from january.

I really don't mean to be negative, but I just don't see why this is on the frontpage of hacker news.

We've got a fair amount of lego train sets, I just wish it was easier to get them to interact with the recent Mindstorm sets. I'd love to program the Mindstorm to control the trains & tracks, but that's not an out of the box option.

Why do it when you can overdo it.

Can't help but think of how much of a pain that would have been to live with. Imagine all the stubbed toes.

Did anyone else get motion sickness watching this?

Meh. It's interesting because it's long. Nothing else of interest in the layout.
