Today I learned about pyrography and a particularly dangerous technique called "fractal burning", where people use high-voltage electricity to burn patterns into wood.

The result is quite beautiful, but I can see why some countries might want to regulate or prohibit it. Personally, I think people should be allowed to take such risks if they choose to do so.

That would be strange for a traditional Chinese art that's probably sold at airports and gift shops.
