I guess it's like churches - if you go to look inside a church/cathedral/synagogue then you pay lip service to their wishes - shoes off, no shorts, no shouting etc. It doesn't mean you have converted or are giving up any of your own beliefs, it's just polite.

North Korea is just one big 'different' place.

Q: How do you know if there's a fighter pilot in the room?

A: they'll tell you...

Lego is very high precision - it needs to be accurate to 2 microns (0.002mm) to fit as nicely as it does. It's one of the more precise things you'll find in a typical house.

I don't think 3D printing is quite up to that yet, even the pro machines like they use at Shapeways.

A lot of the lego-a-likes don't mould to such high precision or with the same quality of plastic, that's why they don't fit together as well.
