I happened to be watching an NHK World doco on the Tale of Gengi, a classic story from the 11th century, and the doco featured the Japanese kirikane glass artist Akane Yamamoto. Akane carefully makes intricate layered patterns in threads of gold foil then sets them into glass.
You can check out the works on her website. They're extraordinary!
