Anonymous Japanese Artist
... made clay whistles in the shape of Physocypria nipponica
This whistle was made by a member of a local community group based at the Lake Biwa Museum in Japan. The clay is from Shiga and the whistle was fired in a small, portable, traditional kiln. The artist visited Dr. Robin Smith at the Lake Biwa Museum one day and asked to look at some ostracods. There were some Physocypria nipponica from Lake Biwa alive at the time in the lab. He later made a number of clay whistles, which represent his impression of Physocypria swimming around. The whistle works very well!
