Into the fold: Origami left by diners molded into art collection

KAMEOKA, Japan - Yuki Tatsumi was waiting tables at an izakaya pub in Japan's Kyoto when something on the table caught his eye - a chopstick wrapper folded and fiddled into an abstract shape.

It was the catalyst for a collection that now includes some 15,000 pieces of found "origami art" made by customers folding the paper sleeves that cover chopsticks at Japanese restaurants.

"The very first one I found just looked like a bit of junk," 27-year-old Tatsumi said, but it made him think.
